I had back surgery at the end of August, so today was the first time I've been able to spend any real time with my small backyard flock, having left their care to my husband. I quickly noticed one of my Ameraucana hens (3 yrs old) didn't look right. On further examination, I noticed that this once beautiful example of a hen actually looked more like a duck, low abdomen, waddle, tail down. Catching her during daylight wasn't easy for me so I had my husband go get her after she went in to roost. I'm not sure if she made it up to the roost. When I checked her out, I found she had a very hard, droopy abdomen, a small amount of white poop stuck to some of her bottom feathers, not blocking her vent. She had been eating, and her vent looked normal. I put on a glove and with a little lubricant, inserted my finger about an inch to see if I could feel anything. Nothing was there so I stopped. I put her in a large box for the night. We'll be off to the vet in the morning. Any ideas or suggestions? I've had lots of small flocks in my life but never experienced this.
