This morning I checked my babies before leaving for work, I moved them out to a big brooder out in the Garage on Friday, and I found my little roo on his back dead... He was fine last night, at about 6pm I checked on them, and I picked him up and pet him for a few, he seemed fine. Now it is cold here at night, around 40 degrees, But I have one of the 250 watt red bulbs about 18 inches above them, yesterday durning the day the thermometer read 93 degrees, but it was only like 55 degrees ouside, so even with a 40 degree night it shouldn't have been too cold. And this bird was twice as feathered and twice as big as the other 2, they are all 3 weeks old. Do you think is was the cold? or maybe a Bug Bite? If it was the cold, I would have expected the smaller less feathered ones to have been affected. I'm sad, he was my Favorite out of the 3.
