Hey all, So I got some Rhode Island Red chicks from Tractor Supply. They're a little over 3 weeks old now,and I'm wondering about one of them. All of them look exactly the same of course,but Shadow is making me wonder. She has different feathers,darker and silkier. Her tail has black in it already. Her body is slightly smaller and so is her head. I don't know if I'm dealing with a rooster or just a different looking pullet. Any help would be appreciated!!
