Brood patch modification
Percentage score of brood patch modification of 8 successful breeders during the breeding cycle
Significant development of the brood patch occurs during the mid-incubation period and complete development is observed at the time of hatching. A near significant value was observed for the regression of the brood patch (p=0.053) during the chick rearing phase.
Development and regression of the individual traits
Development and regression of the individual traits for 8 successful breeders
The degree of de-feathering is higher at the start of incubation compared to vascularization, edema and contour feathers.
Corticosterone levels
Stress levels during natural incubation while incubating (N=8) and rearing chicks (N=7)
No significance in stress levels during incubating and chick rearing stages
Prolactin levels
Unfortunately, we are unable to show the prolactin levels here because the chicken prolactin ELISA kits we tested were unable to detect the prolactin in plasma
