Hello, I have a few questions about the Delaware breed. I had gotten a chicken almost 1 month ago or so for free but did not know the breed. Only recently have I noticed her similarities to the Delaware breed. Pic: The previous owner said she was 4 months old. About 2 weeks ago, I've changed her diet to pellets (as recommended by the store run manager) After that, she shed for a little and her new feathers coming out have turned a beige color on her back. More and more are growing out and she has lost all her tail feathers but 1 since last week. I've been checking for regrowth of them but I cant really see. The last tail feather on her butt seems a little shaky, it looks like its shaking, I don't know how to explain it. Anyone have any tips with this breed / can confirm my bird is this breed? I think she is mixed. Also, her comb is very small and pale. When will it turn the dark vibrant red I see on other hens? Thanks!
