Anyone have any ideas on what's wrong with our hen?: She is almost 1 year old. I noticed her tail was down Sunday morning and moved her into a solo pen. She is eating & drinking no problem. On Sunday her poops were runny and she had white poop over what is usually her fluffy butt. I gave her electrolytes & probiotics mixed in water. She also got her usual food mix (includes oyster shells) and mixed in some DE. As of yesterday, she has normal looking poo but her tail is still down. She seems to be in good spirits, chatty like usual and not weak or lethargic. Her comb is isn't pale. I included a few photos of her, her feathers are a little wet in the pic as I gave her a bath to clean up her poopy butt fluff. Anyone have any ideas on what could possibly be wrong with her? Any tips or advice would be greatly appreciated! Definitely want her feeling better so she can join her friends!
