I have two pens of banty cornish that are now probably two years old. (got them full grown last year). Last breeding season I did not get very many eggs to hatch from my cornish. (all others did fine) This year I want to try again and I have been looking at my roos and they seem very heavy. All one wants to do is eat. I have not seen any "activity" in the two pens. I am wondering if the roos can get too heavy and have problems mating. Should I restrict the food some and hope things go better this year????
