So, I have my first flock of 13-week old pullets, and I will not be keeping a roo. Looking forward to the time when I might want/need new hens, not being thrilled about the idea of brooding again, and having read horror stories about integration, I wanted to ask the experts of BYC: If I were to get a broody, could I slipped some purchased, fertilised eggs under her? What are the odds I'd have a successful hatch? I understand I'd have some cockerels to deal with, but I think I'm okay with that. Would this save me the brooding/integration experience? Would the flock accept the babies as a matter of course (assuming a separation period, of course...), or do you STILL have to wait until the new chicks are adult size to introduce them to the flock?
