Hi everyone! This is my first time on here and I'm hoping I can gain lots of knowledge and wisdom from you. I'm sure I'll have plenty of questions later but here is my first one. I have two Wyandotte chicks both 3 weeks old. One is developing faster than the other and showing her tail feathers. In fact all 3 of my chicks are sprouting their tail feathers but this one pretty girl. Could this be the early signs of a rooster or am I way over thinking this? First pic has no tail feathers. Second pic has them. Thoughts?
