I came across someone who was selling out of there chickens and they had some I wanted. Among the group was a broody hen and her six chicks (about 2-4 days old at the time). I bought them knowing I did not have a proper pen for them away from the other chickens that the chicks could not get out of, so I figured the only way to do it is remove them from their momma and put them into the brooder. I have never lost a chick before so I don't know if these being off of a broody hen has made a difference or not, but these chicks are dropping like flies now. I only have two left today. They are eating and drinking. The temperature has been fine. I am not sure what could be different from any other batch of chicks I have raised except that these are in a smaller cage (a large rubbermaid tub verses a small wire rabbit cage that I have used in the past) with paper towels instead of pine shavings. Are you not "able" to take chicks from their mother to raise in a brooder once they are out with a broody hen? I just don't understand what I am doing wrong. They are not peeping like they are too cold and are not trying to get away from the lamp like they are too hot. They are acting normal until they get really weak and lethargic and die and hour or two later.
