I have an eery feeling that something isn't right. No behaviors have changed at all, but I'm nervous. I believe most of my flock is in molt. Also, a lot of them are suffering from something similar to the picture. The hen in the picture is one of my best layers so far, and I believe she is still giving me a daily egg, but she's got a lot of "stuff" stuck to her feathers around the vent. Given, she's the worst. It started as just a little about a week ago, and thought maybe it was just a messy trip to the bathroom. But I noticed today that it is much worse. Again, the flock act totally fine. This could be unrelated and because he just drank water, but when my dominant cockerel mated this same hen, he sneezed and threw up a little. It was clear and I couldn't even find it on the ground. Maybe he just moved a little too fast after eating/drinking. Poos all seem normal for the most part. I saw one a few days ago that seemed a little bit red, but I saw the poop chart and it was more like the kind that has the tissue in it, which they said was normal. Any ideas?
