Oh dear, so sorry to hear this news! Terrible! Did you get that whopper of a T-shower. From my years of experience when you get a whopper like the one we had, more then likely it will kill the developing chicks. I don't know if its 100% accurate, but another guy and myself can attest to it. Perhaps its the amout of granite we sit on too. Good luck and hope we can get together at some point and talk chickens!!!
