One of my Blue Laced Red Wyandotte pullets is so so sick. I'm not sure she's going to make it through the night. I found her this morning laying on the ground, the other pullets were stepping on her. She smelled horrible and her nose was running. Her mouth was also foamy and she was kind of drooling. She has to open her beak to breath and it looks labored. She also has poop that is liquid, clear/greenish colored. What could be wrong with her? She also had some nasty matting under her wings. I gave her a bath with warm water and grapefruit seed extract to try to wash off the matted nastiness to see what was underneath, and it looked like most of it was just poop or something. There are still a few matted spots, but over all her wings are much cleaner underneath. Pre-bath...you can see she's holding her wings down from her body and there is something gross there. Under the wings...both sides looked like this: After her bath the under-wing area is much cleaner and she smells better. I also wiped off her beak. I have her isolated in a wire dog crate, she's sleeping in a bucket turned sideways with a towel. But she isn't tucked up right, her wings are not against her body and her legs aren't under her, and her face is just planted into the towel. Right after her bath we gave her a syringe full of water with three drops of grapefruit seed extract. Is there any thing I can go to Tractor Supply to buy for her, assuming she makes it through the night? One other bird, a hen that I posted about this morning, also has a runny nose but she is no where near as sick. She came from the same farm as this pullet, but since getting them they haven't been in the same pen together. The pullet was in a chicken tractor with five other pullets. So far they seem healthy. Should I do any preventative treatments for them? I'm so worried everyone will get this sickness.
