I have a bit of a question. I have 14 week old chicks outside in their coop and pen. I have 10 week old chickens in our garage at night and front yard in a play area during the day. How and when can I combine these 2. If you have seen my other posts you know my flock that is outside right now just lost half its members due to gender. I am separating the roo's till their fate is decided at my parents farm. Plenty of room in the coop for all the pullets but there is a good bit of size difference between 10 and 14 weeks. How much longer must I separate them. I have had the smaller ones separated for 2 weeks to prevent any illness from being spread. I am also considering bringing in more pullets to make up for those I have had to segregate. Helpful hints?
