Update:
We had a second Broody (this one is our tenants hen, that's she thought was picked off by a predator weeks ago) - she has 10 chicks!
Grand total of: 26 chicks, and 2 Mama's
They're all together now, both Mom's, all the babies - and doing great together!
We have a small-ish, 2- part coop in our barn, (3 if you include outside access, which we blocked off).
So, put a heat light in ONE side, and left the other as-is, with no heat lamp.
Just keep clean bedding, food, and water.
As of today - all 26 babies are thriving, and accounted for!
Unbelievable
I'll get a pic tonight, been trying not to handle them. And, usually have gloves on cleaning, but will get some of their setup.
