Hi, everybody.
Thanks so much for your replies. The chickens were more like pets than anything. One, in particular, was my five-year-old's favorite. When I lost my two favorites, it hurt. When I saw Snowball, it was like being in a movie or something. Surreal. Just awful.
The reason I don't think it's the dog is because he's an 85-pound chocolate lab and could not have gotten into the chicken house. One of the ones that died was in the fenced area next to the house. He never could have gotten in there. Plus, all of the chicks died in a very short period of time. He spends most of his time in the house with me and the girls. Once I realized they were all dead, I knew it couldn't be the dog.
It wasn't over 100. We live in Pennsylvania, and we haven't had our temps hit 90 yet. It's also been rainy and cooler most of the time. The last couple of weeks, except for the last few days, were in the 70s.
I am still really thinking about the water. I was using a large plastic self-feeder than smelled funny when I first bought it, a real chemical smell. I cleaned it out well and watered the girls, and within a week, the water smelled foul. Not foul like bacteria and decay, but like something else. I don't know what corn smells like when it decays, but it's still an organic material. This didn't / doesn't smell like that. Even when I cleaned out the waterer again, it still had tee same smell. Just not as strong.
I don't know how many times I've cleaned it, but it was always the same thing. But the chickens seemed healthy, so I allowed myself to continue using it. The weather has been cool, and it's never gotten overly warm in the house, even when it was in the 80s, so I've allowed it to get down to within a few inches of being empty.
But when I checked it out last night, the smell inside is so strong that I couldn't breathe it myself. Not like organic decay, but a smell so strong and so strange I can't explain it. Like Draino.
Again, it's been like this from the beginning, even when the chicks were small. I have never had chickens, I've never used self-waterers, and while it seemed really strange to me, the chickens seemed to be doing fine. Happy. Growing. Not showing any signs of distress. So I figured it must be a weird chicken thing.
Has anyone heard of chemicals from self-feeders leaching into water and causing the water to go bad? Or will young chicken feed / corn in the water for a week cause such an intense smell? I have this deep fear that perhaps I poisoned my own chickens by not changing their water as often as I should. I had a 3.5 gallon plastic self feeder that I'd allow to get down to within 2-3 inches before I changed it.
Please be gentle on me. I've spent last night and now this morning crying over it.
