Hello I’ve never had integration problems as each barptch of chicks (chicken math) was 2 week older than the last. These were all spring purchases. I got 4 day old chicks almost 5 weeks ago and the temps are dropping. They are in a bought coop from tsc by themselves. I am just concerned they are going to be cold. I currently have 9 girls and 2 boys all under a year (youngest is 5 mo) in a 10x10 shed. I was wondering if it would be wise to try to integrate the chickies into the rest of the flock in the shed with everyone else or do you think they will be ok in their coop. Keep in mind I’m in nw pa. We’ve had frost and it’s been wet and cold and rainy.
