Thanks everyone.
I built a 3x8x4 foot brooder with heated covered end in the coop and evicted the little ones to the coop Thursday night. (Wife much happier)
Everyone one seems ok. Older ones are at the wire wall all the time. It’s fun to watch.
I’m definitely going to clutter up the run...
I have 6 eight week old chicks in a 8x12 foot coop with a 20x12 foot run.
We have 20-4 week various breed chicks in a large brooder pen in house. I know big mistake but it’s too late now.
Will merging them in three weeks +- be an issue versus merging with older hens?
