If they are huddled, they are cold. Provide heat source that they can get closer to/further from as needed. Once they aren't huddled any more, and staying away from heat source, you can get rid of it.
Maybe it's outside of frame, but it looks like hey dont have any shelter or bedding in wired box?
Chicks are fragile, and death in the first days is not uncommon (I've had very good luck, but I know many dont). Cold, disease, stress from being shipped, super doses of all sorts of meds, birth defects... All you can do is make sure there's clean water and food available, and adequate heat...
No evidence that it does, but some herbs and spices can have health benefits, so maybe alleviating underlying issues (peppers dont "cause" birds to lay, but if they help with worms, etc they may pave way for better general health which in turn could mean better egg production).
Hmmm... were these younger hens that hadn't starting laying yet? If so, the timing sounds like it simply coincided with them maturing and beginning to lay.
There is no evidence that hot peppers activate or increase egg production (studies have been done, and none have found any connection)...
That is not an unusual position for chicks to sleep (I know it looks scary, but they just plop down like that). What would be of concern is the lethargy. If she's eating and drinking, she's probably fine!
50. As hens lay no more than one egg a day, if you want between 25-50 you would at least on occasion get a full 50 eggs. But, since even the most reliable layers dont always lay every day, if you want 50 eggs consistently you would have to get 65 or so hens (depending on breed, you can estimate...
Be clear, with yourself and your neighbor. That means recognizing that your statement that she bought the place because she liked your chickens on her property is likely a huge exaggeration. Nobody makes an investment like that for the neighbor's chickens.
It also means recognizing that even of...
We are in Vermont. My guess, without specifics of your setup, is that you should take down the tarp. Ventilation is the most important winter issue. It's the moisture not the cold that causes most problems.
Water in or out of the coop depends on the system: I have no-drip nipples inside, and...
DE is bad news: it is a respiratory irritant, to humans and birds, and kills insects indiscriminately (so you would be killing off beneficial insects as well as whatever it is you think you might be controlling by giving it to your chickens). The health and environmental dangers are not worth...
Chelation is for heavy/toxic metals, NOT a simple metal nut. Cost aside, it is an intensive and potentially harmful process even in humans: please don't even think about putting your duck through this kind of invasive "treatment."
