We just have layers…3 Orpington (these are our favorite), 2 We had a couple of buckeyes that were mice eating machines, but the Orpington get after the mice to and are better layers IMO.
Growers that worked for Bo Pilgrim told my 6 weeks was the target to be ready for slaughter. At 8 weeks Pilgrim broke even and grower make very little profit. Chickens i've raised didn't have all their feathers at 6 weeks.
