We have a year old Astralorp, Ethel. She was this age when we bought her. She was laying fine for the first few days and then she stopped. She never roosted unless we put her up there. Her vent got messy so we cleaned her a couple of times. It was yellow and runny. Also described here: https://www.backyardchickens.com/t/912771/yellow-goopy-poop Recently she has become slow and pale. She stands in a vulture like stance and looks as though she can't hold her own wings in tight. We separated her and suspect vent gleet. She is still eating (very little unless it is a raw veggie or fruit) and drinking water. WE gave her Epsom salt yesterday. We are just lost and do not want to lose our chicken. Any advice? Thank you.
