Hi all! My name is Robbie. I have had silkies for 2 1/2 years (first time chicken Momma). Last November, Henrietta developed a large bump below her vent. I kept her in the house and doctored her for about a month for "egg bound". I worked with her trying to get her to pass this "egg". No luck. She was stronger and eating drinking & pooing well, so I gradually reintroduced her to the flock. She did great for months. I noticed in October of this year, she seemed to be moving more slowly and was getting picked on by the others. I checked her and the bump had gotten some bigger. Then a few weeks later she would not come out of the coop. When I went to check on her, I noticed flies around her. Yep, fly strike! I immediately got her bathed and doctored up. That is doing great, but bump has gotten bigger to where she has difficulty walking and her poop is clear watery liquid with just a little bit if solid in it. She is eating everything offered, except her chicken food. She is drinking water and her eyes are alert. I was holding her wrapped in a towel last night and she had equal strength in her legs trying to climb onto my shoulder. I am attaching picture of her underside which is swollen. It starts right below the vent and goes to the palm of my hand.
