I've read a bit about moving chickens in together. I thought I would ask anyhow. I have 2 BO's that are about 6 wks old. and 5 RIR's (?) that are about 10 wks old. The BO's are not much smaller than the 10 wk olds (really.......considering the age difference). I need to move the BO's in w/ the RIR's in a couple of weeks, what is the best way to go about it? I already have 2 coops going (one w/ my yr old BR's - 4 hens) and one small one w/ the teens in it. And then a stage 2 brooder in the garage. I need to get the BO's out of the garage. Help.
