I'd keep em around. I have an OEG bantam that I caught wild from an office Park where the physicians were afraid she was going to get hit by a car (and she was all alone laying her eggs in the generator outside). She was completely wild.I brought her home, fed her and she has tamed down quite a bit on her own. She still roosts is a bush by the house though.
She went broody & I let her set on two big std size eggs which she hatched & raised. Games are resilient, hardy, self-reliant and as the other post indicated, they are very good broodies. My little OEG is very predator savy too.
