I ordered 20 biddies from a coop here in south Alabama. Went good for a few days, then we lost 2, 2 days later 7, last night 1. The heat is running around 98 to 100 during the day and 80's at night. We have them in a pen on the porch, they have good shelter, and hay. We burn a 60 watt bulb in the shelter 24/7. No injuries on the babies, just dead. Im so confused, please give me some insite. Thank you for your time.
