I think that 40 chicks in one brooder might be the reason. Better divide them into at least two groups in two different brooders.I have 40 chicks in a very good sized brooder with plenty of space and 3 heat lamps I have a thermometer so it is kept at the right temp and they have plenty of room to move if they get too hot or cold , but so far I’ve had about 5 chicks die and I was just wondering if it’s something I’m doing or if this is normal
The weaker ones will be pushed aside and not be able to eat or drink as needed.
