Hi, I am fairly new to chickens, I have a hen that's acting odd trying to determine if shes broodie or sick. She is lethargic, I can't tell if she is eating or not, Eyes are clear and I don't see anything obvious, I am watching more closely. She is as digging in the nesting box, and started sleeping in it last night. When I opening the coop this morning she came out, I added a floor level box and she went back in and started sitting in in the box for a few hours at a time. I added some eggs to the nest hoping she would sit longer but shes not. I am not sure how the Broodie act, I would have thought she would not move off the nest. Shes a RIR/RIW mix. There is a RIR roo in there so the eggs should be fertile. oh and the other thing is there are 6 of them in there, I was getting 5-6 eggs a day, now 2-3....
