Also, a lady I'm working with says that with her Icelandics, if she rotated them in and out like that, her cockerels would get depressed and not eat. Will this only work with certain breeds that aren't so 'bonded' to their mates? Because, I had considered having a 'barracks' for breeding season, where I would remove my breeding cockerels to for a few weeks prior, then place C. A with hen set A, and C. B with hen set B, then collect eggs for a while, then remove the males for a few weeks, and swap C.A to hen set B.... etc.
I'm not Bob, but I use this coop. I put a hen in each separate pen. I take one cock bird and move him from pen to pen (hen to hen) each day. When I collect each egg, I write the leg band # of the hen, that laid the egg, on the egg.
My cock birds are quite happy with this method. They actually start looking forward to being picked up and moved to a new mate each day.
