I have a mixed flock of different breeds, including a some black copper maran cockerels who are 8 weeks and a Japanese bantam pullet who is 4 weeks. Anyway, I'm planning on keeping a rooster and what happens when they mature and I'm letting an 8 lb. rooster mate with a 1 lb. hen? I really don't want to rehome the pullet because she is sweet and I mainly keep roosters for breeding purposes, but it's necessary for me to rehome one it will be the Japanese bantam. My question is, can I let an 8 lb rooster mate with a 1 lb hen? I don't want to take any chances of mortality. Any answers appreciated!
