I am new to turkeys. The first ones I bought is a trio of royal palms (two are blue). They are spring hatch and big and no doubt as to who is who. Then came the 6 poults that are about 10 weeks old. Bourbon reds, and they all look the same to me. One is growing a bit faster and getting a bit lighter in color, but still nothing that stands out as different. So how do you tell the sexes of poults?
