"Hmmmm...didn't know Roos were layers."
LOL!
I think of my birds as either layers or meat birds. The roosters are from eggs hatched from my layers ( I have a layer roo- i.e. a large Production Red rooster for my layers) and a meat roo (i.e. a Ranger rooster for the meat hens). So I didn't mean the roosters would lay- I just meant they were extra roosters from my layer flock and not my meat flock. Since I am culling roosters that are NOT meat birds but from layer stock my question was: when should I butcher these guys since they don't develop as fast as meat birds?
Anyways- Thanks donrae for the answer. Really, 18 weeks is too long to feed them- I think I'll just butcher at 12 weeks and not have a lot of meat.
