Ok so I have 6 chicks right at 4 weeks old. Four blrw and 2 olive eggers ( marans x) all straight run. I am positive at least one of the blrw and more like 2 are Roos. The olive eggers have me stumped, but just by their behavior I'm leaning towards Roos. Anyway.... I'm wanting to get a couple older pullets in the 3 - 4 month range. I am worried about combining the different age chicks. My current chicks have been going outside on warm days but haven't been in the coop yet and I would of course quaranteen any new girls I get. I'm also thinking the fact that the coop would be new to all involved would be beneficial... Neutral territory. So what do you think, would it be too difficult? I really don't want more young chicks right now... I want them out of the house... Haha
