Where did you get them?
Asphyxiation? If a tub is tall, there might be lack of fresh air on the bottom. Need circulation.I actually combined chicks from three different feed stores. The thing is - this happened last year too so I must be doing something wrong.
They are in a huge rubber trough with a chicken mesh lid on top (weighted so cats don't get in), heat lamp and on those bedding pellets - same pellets the feedstore uses. They're eating StartNGrow medicated chick feed. Getting water changed 3 times per day and they're sleeping a little ways from the lamp, so not cold, even at night.
I hate this. They are my 10 year olds and he gets his heart broken once a week.
