I have a little Buff Orpington that seems to be very slow in growing and has little feather growth. When I got her, her wing feathers were frizzy and still are. This is my first time with chicks so I don't know what's normal or not for growth. All the others who are just a week or two older are all pullets now but she still has chick fluff all over her body. I noticed the other day that she is just now starting to get tail feathers. She still acts like the other girls. Eating, drinking, and running around. She loves going outside in the chicken tractor chasing bugs and doing her dirt bath. She still spends a lot of time under the heat lamp however. She does not get picked on however. In fact the other girls are starting to mother her and cuddling her at night. Its very sweet. She is a very sweet chick and I like that she is still accepted with the other girls. I have heard that roosters can be very slow growing and their feathers come in slow as well. Should I be worried about her?
