My little bantam is sitting on 6 eggs, I have her in a dog crate so she can be on her own and be locked in at night, the door is open during the day. She has only been sitting on the eggs for a couple of days but she isn't getting off to go to the toilet. I lifted her off today to clear away some of the smelly mess under her and her fluffy back end is rather covered in the mess. Does anyone know how I could clean her. Do hens usually get off their nests for short periods to do their business and then get back on or can they just sit there for the entire 21 days?
