Can you post some photos of her?Thanks for the replys. She is nearly 3. She isn't molting and I don't have a rooster and havnt noticed any bullying amongst the girls. She has just gone broody so I now have her isolated in a DE free environment. I had a look inside her ears but will give them another look soon. She doesn't have any neck issues while she is sitting. I've started to feed her thiamin and vit e rich foods and added some b vitamin crushed into her food. Havnt been able to get vit e tablet yet. Hopefully she will improve.
