We lost our 2 month old gold wyandotte last night. Her buddy died last week. Now we have one left...with 4 others coming next week. The 2 that died were eatting, pooping and acting "normal", but when they would fall asleep, they were really limp looking from the beginning(we've had them a month). What could I be missing/overlooking? We house them in my garage and they have a light at night-it's a steady 60-65 degrees in there without the light. They have free access to food/water and roosts in there cage. And we take them out mid-late afternoon when it's warmer outside (for about 20 minutes)and let them be chickens(look for bugs, scratch in the yard). The feed we use is the chick medicated stuff from Tractor supply. Thanks for any help.
