I am fairly new to chickens and need some advice. I have 24 4 1/2 week old chicks in a 12x10 coop with a heating pad cave. Their large run will be completed in the next 2wks. I have the opportunity to acquire 5 8wk old chicks that are a breed I very much want to have. They are vaccinated and are living in very clean conditions currently, they appear to be very healthy chicks. I can't see a way to properly section off my coop right now so that they couldn't fly over and get in with the younger chicks. I plan to eventually section an area off, but it's not in the $ or time budget right now. I am thinking I'm probably just not set up to take these chicks now, but really don't know. I don't want to risk the younger chicks being injured by the older ones, but I don't honestly know if at theses ages it is an issue or not. Thank you!
