Of our three 3 month old pullets (2 easter eggers and 1 welsummer) 2 just died, one EE (Cleo) and the Welsummer (Goldie). The worst part of all this is the thought that we could have prevented it. The whole, "What if we would have checked earlier?" "What if we would have cooled them off more?" ugh... it's torture! We were so looking forward to a bunch of blue and chocolate eggs in a few months. I think I'm more upset than our 4 year old daughter. So, if it is expected to be unexpectedly hot where you are (like it has been here) then double check on your girls. Make sure they have LOTS of cold water and misters if needed!
