I am somewhat new to keeping chickenS, especially American/Euro breed. My question pertains to my small flock. I just acquired 6 Buff Orp pullets/hens and a 3 year old Buff Orp rooster. I want my hens to raise their own chicks and was wondering if 1 rooster is enough to breed with 6 hens or would I need an additional rooster? Thank you all so much
