It is hard to name them when you don't know if it's a he or a she. I bet you'll be able to tell within a month. We named our turkey Harriett, but it ended up being a Henry.
We had ordered all pullet chickens, but ended up with a surprise SLW roo. My daughter kept seperating him thinking it was a dominate hen picking on all the other girls. As time went on his comb was bigger and redder and he was taller....longer legged.
