I have a 3 yr old Buff Hen that hasn't quite been acting normal. For the past 2 weeks she goes into the nesting box at night instead of the roost and starts breathing heavily and her comb and wattles go purple. She is also VERY fat. Almost as if she is bloated. I haven't seen her laying eggs and we have been getting 8 eggs a day (1 green, 1 white, 6 brown) from the 8 brown egg layers and the green and the white. Other than that she has been acting normal during the day. There is a hard spot (to the touch)just above her vent (it's not an abcess). Please Help!
