I picked up my 25 meat chicks on Wed afternoon. There were 27 of them- two bonus chicks, I guess. I am using the Mama Heating Pad method in my brooder. On thursday morning- everyone ok. 11 am -all ok. 2 pm- one dead chick laying dead under MHP. Friday all good. Saturday morning everyone good. 11 am still good. 2 pm good 4pm another dead chick laying under MHP. Whats going on? Can you help? No one seems sick or struggling- they are booting around like crazy. Tons of space, heating pad is on one end of brooder. Good ventilation, food, lots of fresh water. shavings are about 2 inches deep. Im at a loss. Is it possible they over heated and were too dumb to get out from under the MHP?
