Hello! I have 4 adult chickens (3 sex linked red and a white leghorn) and just acquired three 7 week old chicks (two buff orpingtons and a barred rock). Currently, the chicks are still eating medicated chick feed. They are living in the same run as the adults but within the confined of an extra large dog crate. They have a cat carrier inside the dog crate for shelter. They have been living outside for 2 weeks in their previous home. I had planned to keep them in the dog crate (the wire kind with the bottom removed so they can eat grass that grows between the wire). How long should I keep them separate from my adult chickens? A week? A month? Your thoughts would be most welcome. Thank you!
