I hoping it is just a freak incident but today I think the heat claimed my week old silver seabright... I found him laying in the corner appeared to be sleeping... I live in Oklahoma and this summer heat I think is just to hot for the little ones... which for me is hard to imagine... There temporary residence is in our travel trailer in a old rabbit cage. We placed fans in the window to keep it cooler... Temp inside is between 110 and 100 through the day and at night when the temp falls we put the heat lamp on them. I just believe the heat is to much for them... But the others all seem fine... Does anyone have an idea of how to keep them cooler... I think they have even been getting in their waterer to get cooler. I replaced it with a quail size to keep them out of it.... did not want to risk any other water and wetness related issues.... Just trying to keep my little one at the right temp!!! The heat claimed one of my RIR hens last week so heat was my first guess.
