Thank you for the advise. Pluma is 4 years old, I have dusted her twice for mites since she has become "slow". I had fumigated the coop for mites last week. (with mite spray and powder). Her crop seems empty, I can feel her breathing bone, she has always been small, she is one of the 2 less leaders in the flock but even that she has always eaten and drunk well. They have always fresh water in their pen, and in these hot days, they also had water in several places in the backyard, where they are allowed when we are at home. She has never been a good layer, laying only a few eggs a month. She probably laid the last one 3 weeks ago.
I cannot feel any swelling in her abdomen, she is not visibly hurt. Her eyes and nose are fine, no drainage, she is breathing normally until I try to feed her, then she is breathing heavily with her beak open. I think that is stressing her.
She is not drinking nor eating on her own. I started giving her some baby bird feed yesterday as it was suggested to me. I still give her about 15cc of pureed flubenvet when she lets me (although half of it ends up on the floor or all over her).
Her poop is small, looks normal, no solid, green and white.
She has been exactly the same since Thursday morning, so 4 days now, yesterday maybe a bit more tired and sitting down a bit, but pretty much the same.
Should I also do water on its own?
I will buy fenbendazole today and can try with that too.
I really appreciate all your help.
