“…Overall hatching rates were 87.9% for guinea fowl eggs (Table 1) and 79.0% for pheasant eggs (Table 3). Reported hatchability rates of guinea fowl and pheasant eggs widely vary, with rates of between 45 and88% reported for guinea fowl (Royter & Arutyunyan, 1990;Saina, 2005;Moreki & Mothei, 2013;Yamak et al, 2015a) and between 41.54 and 96.7% for pheasant eggs (Esen et al, 2010;Demirel & Kirikci, 2009;Kozuszek et al, 2009). Factors that affect hatchability have been well described in previous studies and include male-female ratio and nutrition of parents, as well as egg-storage conditions (Yamak et al, 2015a;Kozuszek et al, 2009).…”

“…Similar variations have been observed in guinea fowl, with reported hatchability rates ranging between 45 and 86% (Yamak et al, 2015a;Bernacki et al, 2013;Royter & Arutyunyan, 1990). Considering the value of pheasant chicks and guinea fowl keets, together with the low egg numbers and variations in fertility and hatchability, successful incubation of all eggs is particularly desirable in these poultry species (Demirel & Kirikci, 2009;Yamak et al, 2015a).…”

Successful incubation affects the number of healthy chicks in all poultry species. This study examined the effect of eggshell thickness on the hatching rates of guinea fowl and pheasant eggs. In total, 964 guinea fowl and 1,728 pheasant eggs were used in the study. Eggshell thickness was measured directly with an ultrasound gauge. Thicknesses ranged between 0.27-0.47 mm in guinea fowl and 0.24-0.49 mm in pheasant eggs. Incubation periods were 28 days for guinea fowl and 25 days for pheasant eggs. At the end of the incubation period, unhatched eggs were broken to identify the causes of embryonic mortality. Eggs were classified as thin-, medium-and thick-shelled, and hatching rates were calculated as a function of eggshell thickness. Differences in hatching rates of guinea fowl and pheasant eggs with different shell thicknesses were not statistically significant (p>0.05).

A. Şekeroğlu, H. Gök, and M. Duman. 2016. Effects of egg shell color and storage duration on the external and internal egg quality traits. Cien. Inv. Agr. 43(2):327-335. The present study was conducted to investigate the effects of storage duration and egg shell color on external and internal egg quality traits. Eggs were obtained from 29-week--old ATAK-S layer hybrids reared in a traditional cage system. Storage durations were set as 0, 7, 14, 21 and 28 days. Shell color was classified as dark (59.00-67.99); moderate (68.00-70.99) and light (71.00-79.99) using the ∆E values of the eggs. The storage duration significantly affected the egg weight (P≤0.01), specific gravity (P≤0.01), breaking strength (P≤0.01), shell thickness (P≤0.01), shell weight (P≤0.01), surface area (P≤0.01), albumen index (P≤0.01), yolk index (P≤0.01), Haugh unit (P≤0.01), yolk color (P≤0.05) and albumen pH (P≤0.01). The egg shell color significantly affected the specific gravity (P≤0.01), breaking strength (P≤0.01), shell thickness (P≤0.01), shell weight (P≤0.01), albumen pH (P≤0.05) and albumen blood-meat spots (P≤0.05). The current findings revealed that the eggs should be transported to consumers as soon as possible, and further studies should be performed to darken egg shell colors. It was concluded that newly laid dark colored eggs had the best quality.

“…Eggshell colour was also found to have different effects on pheasant hatchability (Mroz and Pudyszak 2000;Krystianiak et al 2005;Kozuszek et al 2009). As demonstrated by various research results, egg fertilization and hatchability rates in pheasants tend to vary and often remain unsatisfactory (Demirel and Kirikci 2009;Kozuszek et al 2009;Esen et al 2010). Therefore, scientists and breeders keep looking for ways of improving reproduction parameters of these birds.…”

A comparative analysis of reproduction parameters and hatchability results of pheasants raised under two different housing systems (cages and aviaries) was performed. In the first system the pheasants were housed in 420 cages, 3780 from the total were females. In the second housing system, 3200 pheasant hens were placed in eight aviaries, where 50 cocks and 400 hens were kept in each. The following parameters were calculated: laying rate, the percentage of hatching, small and cracked eggs, hatchability from set and fertilized eggs, dead embryos up to day 8 of incubation and, finally, dead embryos after day 8 of incubation as well as unhatched, crippled, and weak chicks. The laying rate for the whole period of reproduction in pheasants kept in cages was significantly higher in comparison with aviaries (59.6 vs 27.2%). A higher (P ≤ 0.05) percentage of small and damaged eggs ( -x = 13.6) was recorded in aviaries. The percentage of dead embryos for eggs derived from aviaries, up to day 8 of incubation, was also significantly higher ( -x = 4.7%). There were no significant differences between the housing systems with respect to the remaining features. The results of the investigation made it possible to conclude that pheasants kept in cages were characterized by a higher laying performance with fewer eggs unsuitable for incubation. A lower mortality of embryos during the incubation process was found in eggs derived from pheasants reared in cages. Although there were no significant differences between the analyzed housing systems in terms of hatchability, a higher laying rate for pheasants kept in cages implies that more chicks could be obtained from every female.
