I received 6 Ameraucana chicks from Ideal on 8/8. On Friday morning, I found 1 dead in the brooder. On Saturday, 2 more were dead. I thought that maybe they were getting too cold. The overnight temp recently dropped from the 70s to the mid to low 60s, but they have a heat lamp. So I moved them inside still using the heat lamp. The temp under the lamp is about 85-90. This morning, 2 more were dead. The only thing I noticed was that one (that died today) had bloody poop yesterday. I know that is bad, but he was the only one and he was one of the last to die. There are 4 other chicks the same age in the brooder, all fine, and 4 that are a week older, all thriving. Could there have been something wrong with that batch of birds? BTW, I cleaned the brooder this morning and changed out all the pine shavings. So my precious tinted egg layers that I coveted so badly are down to just one.
