No tail feathers for months

[TuscaloosaForestLadies]

New to chicken raising and one of our girls lost her all her tail feathers basically overnight. It happened in December so we presumed it was her first molt but they have not yet grown back and it looks the same as the first day she lost them. Otherwise she's normal, eating/drinking/laying as normal.

She's not really one that can be handled but I finally got a good picture and it seems like the feathers were broken off low? Any ideas? Is this something we should be worried about/helping her fix?

is there any pecking? do you have a rooster? how much calcium is on the diet?

No pecking that I've seen & no rooster. We feed Purina high protein crumble with oyster shells.

that is odd....

Chickens feathers are 80% protein so you may need to feed them more than what you feed your other chickens, You can try bringing her inside and give her a bowl of some food for herself, She might not be getting enough food to regrow her feathers.
