We lost the pullet over night. Im so incredibly sad. I feel like i let her down. We're going to do a better job about keeping the shop closed more often and keeping fluids off the gravel. Im almost certain that's what did this. Everyone else is 100% fine. The other hen seems to be fine too but still keeping a close eye on her.
I'm sorry for your loss.I just spoke with my husband who was home with them all day yesterday, and he said she stayed on the house side of the property literally all day and drank water constantly. Then at night time he had to carry her to the coop because she wouldnt go on her own. He set her by the water in there and apparently thats where he found her this morning. Does extreme thirst happen more with a toxin or illness usually?
Drinking water constantly, I associate that with crop issues, but I'm sure there are other things it could be. @azygous should be along in a while.
This may be hard for you, but if you still have the body, can you either send the body to your state lab for testing or do an information necropsy yourself?
You may not be able to find anything without testing, but looking at the organs, crop, intestines, gizzard, etc. may reveal something. A state lab, of course, is more thorough and gives a report of their findings. If you think you can do it yourself, the video is very helpful. Take photos and we can try to help you too. I'm sorry.
