Molly is 3 years, very active. About 3 months ago she started molting and is still going through that process. Yesterday I saw her standing, puffed up. Not moving. I checked her over, didn't see anything out of the ordinary. I checked her this morning for sour crop and impacted crop and her crop was empty. Today she has some secretion coming from her vent that makes me think that she has a yeast infection. I read that yeast infection and impacted crop go hand and hand. We are in Texas and the weather is in the high 70's so she's not in a cold environment that would make her puff up to keep warm. Was thinking maybe parasites but I am currently on a 5 day regiment of safeguard in the water for the whole flock. Any thoughts here? I'm lost as to what to treat her for.
