Wanting to breed my best Border male to several hens, I placed the four most ready hens with four nest at various position in a flight cage. The green hen quickly picked the right hand corner and proceeded to defend her nest when any other hens were in the vicinity.
This Border hen picked the safe middle territory and was unconcerned about Border Wars!!
Unfortunately, the cinnamon variegated hen immediately picked the same nest!!
Both began to lay, first one and then the other in the right corner nest! The green was a bigger trouble maker, so I moved her and the original nest to the identical flight right above in the same corner. The green hen was very happy with her new identical location just the flight on top of her previous flight. The cinnamon variegated hen accepted a new nest in the old position with the other hen nesting in the middle, they are happy setting on fertile eggs while those in the top flight are completing their clutches.
This hen joined the green border in the top cage and no problems between them. Meanwhile, the busy male is frequenting this flight and another with three more hens!! This selection method efficiently save time as truly serious hens go right to work and the others can be moved on to another cage with nests all ready for them.
Hope you had a Happy Easter! My children and grandchildren enjoyed a feast with us! Wish you'll were here!!
