two primary reasons for the birds, first is pets, second reason is for eggs. I want to get 5 total. I have everything set up and local feed store has 3 choices, so please help me decide. I live in South Eastern NC so the winters are mild. I have an acre for them to free range on during the day time and will be locked up at night. Here are my choices Black Sex links, Americanas, Buff Orpingtons. Please help on this, I would like to go and pick them up this week.
