I grossly miscalculated the time to raise baby chicks and mix them in with our adult hens. When I brought home chicks in January, I only looked ahead as far as how long until they would feather out and be coop ready. When I looked at the recommended timeline for integrating a flock - 16 weeks - I was horrified. Luckily I found help here on BYC. We moved the babies into the coop three nights ago and so far so good. Thank you thank you BYC!
