:,(. Of all nights to come home to this. Spent a nice evening with 5 of my 6 children and their significant others, 9 Grandchildren, two nephews, one sister and my precious momma. Came home and checked on my Chickens outside...it's only 30 in their coop brrrr!!!! But they are all cuddled up and warm. Came inside greeted by a bouncing and happy doggie. Checked on my Bitties in the brooder... found one dead and one so weak it probably won't live the night. They are the two that had the pasty bottoms. Now there are three more with pasty butts... What can I do???? What can the problem be?
