We had a dozen 4 weeks olds in a dog crate on the covered porch. They had a heat lamp on them with a tarp over it at night. It has been warm here. last night a storm front blew in, earlier then was forecasted and the temp dropped 40 degrees. The tarp blew off and the outdoor rated heat lamp exploded. So I woke this morning to 4 dead chicks and 8 very cold very wet chicks. The 4 dead ones were markedly smaller than the rest. My son and I spent an hour drying chicks and most are now doing well. 2 are still iffy, but are starting to perk up. We have them inside under in our new chick box under a heat lamp. What else can we do for them?
