I just got 100 chicks from Ideal 3 weeks ago. I had a few losses (trampling) among the smaller birds, but I got everyone sorted out ok. I was quite happy considering that they had travelled from TX to PA in 20 degree weather. So this new bunch is baffling me. The only thing I can think of is that maybe at some point in transit one end of the box was warmer than the other, so those chicks didn't get as stressed out. But why, if you're a stressed chick, would you act normal for 2 days and then curl up and die? Poor little things--I wish they could talk and tell me.
