I have one of my favorites, Thelma who has stopped eating. She drinks but I can’t even entice her with treats. I noticed that her beak looks a little longer than the other girls. Is in too long and not allowing her to eat?
No, it should be just fine! With the picture that you attached, you chickens beak doesn't look that bad at all! I could be wrong, that's ho it looks to me!
Hope this helps, Good luck!
It sounds like she is not feeling well, I don't think the beak is her problem.
Check her crop first thing in the morning before she eats/drinks to see if it has emptied. When was the last time she laid an egg? Feel the abdomen for bloat/swelling or feeling of fluid.
What does her poop look like?
