I have a pullet about 6 months old that is sick today. She doesn't want to move. She is standing though and not sitting. She has a very poopy butt. She seems to be breathing heavy. She does not have her feathers ruffled nor does she close her eyes like a sick bird. She seems alert. I have soaked her in epsom salt. I have tried to get her to drink, electrolytes and vitamin fortified water. I don't think she has started laying. They free range but to the best of my knowledge she is not laying and her comb is not very red. Any ideas? Does it sound like vent gleet? I am new to chickens and learning everything the hard way by going thru it. Would appreciate any help or advice.
