I rotate my cocks into my White flock every laying/brooding cycle because I am trying to hatch every egg laid this season. I have my hens synchronized to lay and brood around the same time. Any stragglers are separated from the flock until they get with the program. It's working well for me but I only have three males and five hens right now to work with. I suppose two months in and one month out is how I do it.Hi glad you asked this question and dont mean to hijack your post,but I was wondering how long you leave your birds in the breeding pen for gor best chance of fertile eggs?
These are my first results with this system. The second pen is just finishing up laying this cycle and getting close to broody again. I just candled sixteen eggs from cock #2 in the incubator and have 75 % fertility. Cock #1 was 100% fertility. I will wait another month before putting cock #3 with the five girls.
