I currently have 5 -1 week old chicks, I was offered 2- 4 month old hens RIR/EE. I was wondering if I should take this offer or past? I just didn't want to endanger the baby chicks. They are in a brooder and I planned on keeping them in there until at least 5 weeks old. If I do get the 4 month olds when should/how do I intergate them to the baby chicks? Your opinion or thoughts on this would help allot. Thanks.
