This is my first time trying to raise chickens I have mostly silkies and I think not sure on the other two. I work in preschool and decided to bring home the chicks that hatched in our room. Looking forward to the fun.
I can see silkies and what appears to be 2 Barred Rocks(or other breed with barring) If you want them sorted out wait till 6-8 weeks and then post individual pictures of your chicks at "what breed or gender is this."
