I have 19 Blue Laced Red Wyndots. We lost 1 yesterday and we thought it just ended up on the bottom of all the birds cuddling up to sleep but then today I lost two more. One this morning and one in early afternoon. My daughter went outside to seperate the chicks from the rest of the birds to bring them in the house. She went inside to get a cage and back out in about 10 min. and the 2nd for today had died. Could this be Heat Related. It is about 85 degrees but the chicks are in dog kennels that are covered in tarps for shade. The sides are open and they have plenty of water. All the rest of my chickens are find. Only the 3 BLRW's have died. Any Ideas???
