I have this posted in the chick section as well, but I am in need of a little advice. I have three 9 week old chicks that I will be putting with the flock tomorrow night. The flock consists of 1 RIR roo, 1 barred rock hen & 1 frizzle banty hen. I've moved the "flock' into a temp pen in my garage directly next to the brooder with the chicks so they can get to know each other. I did that today. Tomorrow I will scrub the coop & then in the evening I plan to put them all together in the coop, & I will let them out in the morning. I plan to have an area where the chicks can hide that the full sizers can't reach. Now that I think about it, I should probably do that in the coop as well. If I do that they should be fine don't you think? Am I crazy for mixing the flocks? As my Buff Orp. cockrel matures my RIR roo is history, but they are so small now, with so few birds I dont' think that will be a problem in the short term. What do you think?
