So all of the meat chicks were killed and partly eaten by a raccoon pulling them through the chicken wire siding on the coop. I put two courses of 1x6 lumber along the base and ran electric fence wire along the bottom and top of the siding.

Last Saturday I was given 3 pullets, an Americauna, a Rhode Island Red and a Black hen that I've not identified yet. All three survived while the meat birds were being killed.

Laying chicks were put in the coop last night. All survived.Chick weights (gm) at 30 days age:
