I have 4 confirmed 16 week old pullets, one more might be a pullet, might be a young roo. Just got 5 more chickens, 4 confirmed 2.5 year old egg layers, one 4 year old rooster. No signs of aggression from anyone(some evidence of picking or treading on the older hens, but have not witnessed any agression, and thinking if it was pecking it might have been stress or boredom induced). The older birds are seperated from the babies by chicken wire, both flocks of 5 birds have nesting boxes, and perches. The older birds were moved yesterday, (like in boxes, in a car moved) so I really don't expect to see eggs from them for at least a few days. The pullets had an egg this morning. There are 3 BSL, and 2 PR. The bird that is possibly a young roo is one of the reds. The egg was brown. How do you know who laid it? And for the older birds, there's a barred rock, 2 red stars, a golden star hen, the roo is a golden star, and he said the other hen is a buff orphington. How am I going to know who the eggs are coming from?
