If you want your cockerels to get along make sure you run a mature cock with them with no more than one hen. It's the only way to be able to retain your cockerels in good confition up until the proper age to cull.I killed 2 of my roos at 12 weeks old. They were constantly causing trouble. Unfortunately, they were the smallest 2 roos. They dressed out 2.5 pounds each. They tasted good. Things were more peacefull with the flock with them gone. Other 2 I roos got along pretty good until about 16 weeks of age. Shipped 1 roo off. July 10th, right at about 19 weeks got 1st 2 eggs. Couple days later 1 hen dies. Have 3 hens and getting 2 eggs a day. 1 hen, scooter hasn't quite got it figured out yet. She sits on nest for awhile. No egg when she gets off. Both Wanda and Marsha started out laying small to medium size eggs. Wanda is now laying large eggs.
