Hi have three australorps no rooster two are laying but one just sits in the nesting box 24/7 that she is getting bald underneath! She has not laid a egg yet either, I get Tina and lock her out of the coop and then she goes crazy with her cackling and running around then does a gaint poo as she has been sitting all day and I mean gaint!!!!!! As soon as she gets a chance as the noise I worry about the neighbors I let her back in and straight back to the nesting box and shuts up. Please can anyone help as new to this and worried about what to do? Is she egg bound if so how do I check?They have a good diet and fresh water and plenty of fresh scraps and pickings.
