We just got our first chicks two days ago, one Americana, one black Australorp and one buff Orpington. Yesterday we came home to find the buff Orpington had died. We quickly replaced her (each of our children had chosen one as their pet), but now today the Americana is panting and not moving much and not cheeping. She's pooped and doesn't look like she has pasty butt and I've tried several times to move her to the cooler part of the brooder (the temp is 95-98). What am I doing wrong? She was very active last evening and seems like a different chick now. Any recommendations are appreciated!
