I know that it's ok to breed mother to son. My question is; if they are never separated, will she go into heat? I'm guessing yes, but there are no signs yet. There is a gap between their sides of the cage where he jumps through. He is approximately 5 months old and they still curl up together at night and he rarely stays on his side of the cage. I want to breed them because he has perfect Dutch markings in a tan color instead of black and hoping to get more like him. Just not yet.
