So sad. The heat here in Arizona is unbearable this year. I have no fly issues, thank goodness, I think it’s to hot for them to survive. My husband added a mister in the coop nd also put a swamp cooler at one end to give them a little relief. I lose one of my gold laced Wyandottes. So far only casualty to this heat. Good luck with everything.Its so damn FAST.Im sorry ur going through it. Do you think you can save her?
