I'd suggest a meat bird then. They grow so fast its like doing them a service to give them a great home for two months and then you get extra wonderful meat and they don't suffer from all the health problems. You can then really bond w/your egg layers for a longer time frame.
I felt some of the first flock of cornishx I butchered were so healthy and beautiful I wanted to keep a cock and hen. It was proof to my eyes when I butchered them with the others that if I'd done so, it would have been all for nothing as internally you can see damage when externally you could not.
Today, we butcher the second flock of cornishx along w/some very aggressive RIR's that I just brought home from their original home, just three nights ago- I won't feel sad about doing these RIR's, they are going to be put out of their miserable life and I'll still enjoy all my kind, cheerful and beautiful egg laying (purebred) flocks.
I plan on butchering the following weekend, too, the remainder of the poorly kept, canniballistic RIR's I recently got- when its time, its time.
I am also prepared to defend my favorites and most likely will keep a few way past time in the future...but those are the egg layers w/their roo's- unless there is no apparent cure for unwanted behavior or illness.
