I butchered a couple cornishx at well over the normal age, and I was shocked to see the innards stuffed with fat---barely enough room for the organs. I do have 2 laying now-- guess they are not too fat.My bad....make sure they are not fat. Missed a word. I've noticed with my aseels, Cornish and my bucks that overweight hens don't lay as well. Heck, with my aseels and Cornish; they won't lay at all.
