Can five week old chicks be put in a coop? We have them in our brooder and they are outgrowing it. We have six chicks. We live in Western KY and they weather this week has been in the upper 80's. We were planning on putting them in the coop today. Next weekend the weather is going to drop to 40-50's at night. We do know we may have to put out a heat lamp next weekend. We just didn't know if they are too young. Thanks for any and all help! We are new to this.
