I was going to ask a similar question, thank you for taking the lead! My flock started out innocently enough, 8 total, 4 black star sex-links and 4 leghorns. We wanted eggs...well I got the bug badly, and yesterday when
TSC opened its chicken doors, I went and got 6 more....1 Bantam rooster (lets hope the teenager next in line was good at what she did), and 5 cornish rocks. I was worried about the one week difference, but when I got home it was fine. I put them in the brooder with the layers and there was no fighting and no bickering, they even snuggled up under the lamp together.
Now I have 14, even if some are only for a short time, and will be building my coop this weekend. I live in Maine, we are still dipping into the 20's some nights. When is it the right time to put them outside? I can see how keeping them inside for a few days will set that place in their minds as "home" and I am not terribly worried about when they are out during the day, the run will be well protected by the 80 pound staffordshire terrier and a rugged fence.
I was thinking as soon as the layers feather out more, 2 more weeks...the meaties are going to grow quick I know, but what is a good time? Thank you!
