When birds die in short order for an unknown reason, the appropriate course of action is to have a necropsy at a poultry lab. That is the only way to know for sure.
What state/country are you in?
I'm not sure her intention for covering the ground inside the run.
I don't think it is a good idea. First of all, there likely isn't a need. Secondly, chickens scratch in the ground all day long, every day. Having any wire on the ground is a good way to end up with bumblefoot as they get a cut...
You should return it to where you found it. The mother may be looking around to feed it. Since you don't know how to care for it, likely a mistake to pick it up in the first place.
This time of year, fledglings tumble out of nests all over the northern hemisphere around the globe. Probably...
Perhaps someone else can come up with a magic potion. I've never heard of any. At least nothing I would want to use on feathers while simultaneously preventing more skin contact. Perhaps if you were to use elbow length rubber gloves and use a baby shampoo or some other conjured blend.
I don't...
If one knows weight loss has been insufficient, it is important to make significant changes in RH. Just dry it out as much as possible. Humidity isn't a set number. By that, I refer back to natural incubation. A hen doesn't have a hygrometer and she can't control weather. She has to make do. She...
I thought photosynthesis occurs with a certain amount of light so I think moonlight can be sufficient.
Most plants certainly don't need direct sunlight. Any ambient light of sufficient candle power can cause the process.
Won't help. It is supposed to etch and harm the exoskeleton of things like slugs. But not something as microscopic as a coccidia protozoa. They are about 1/10,000,000 of a meter in length.
Even vets and vet technicians with good microscopes sometimes have trouble identifying them.
After the initial shock, lone birds, especially lone hens tend to take chicks under their wing and soon watch over and guard them. I've even had cockerels adopt baby chicks after living alone for a while. Chickens love friends.
The best is to give them plenty of space.
Oh, then you don't want to slaughter early. That would be like eating squab with even less meat. So you'll need to wait till they are a minimum of 15 weeks to get any size on them. That aging will create 2 conditions. Unlike Cornish X that only live 6-8 weeks, they haven't had time to run around...
From the looks of it, you could use it for chickens. Like everything else, all things in moderation.
However, I should make you aware of a far superior product to boost the health and nutrition of chickens.
It is Nutri-Drench. They are formulated for a variety of phylum, class and species...
