Hi everyone, I'm a first time chick mom and I have a Speckled Sussex who feathered extremely slowly, and is just starting to get tail feathers at just about 12 weeks old. She's very feisty, but her comb doesn't seem large compared to her flock mates. I was a little worried she wasn't a she a few weeks back, but am really wondering about the incredibly slow feathering. She just got feathers on her back around two weeks ago. Is this slow feathering normal? The other Speckled Sussex I have feathered at the same rate as my Welsummers. Any ideas?? Thanks!
