My broody hen is sitting on i assume 4 chicks now and some eggs. Last night, i had my hand under her (i should leave her alone!) but right at that moment she had explosive diarrhea right in the nest. I cleaned it up best I could and left her alone. This morning, she is turned around so her behind faces outward, she is trembling like she is cold and her head is low, from what I can see. It has been raining and cold for 2 or 3 days now. Do you think she could be sick? Would a heater in the coop help to dry and warm the air a bit? Is there anything I can give her? I am worried about her and her babies.
