I have a buff orpington seems to be lining the nest with her own feathers so that when the egg comes out they are sticking to the outside intentionally. She is the only one doing it. It is not an excessive amount, but it seems a little odd. It has happened about 6 times now. I always know which egg is hers because it will be covered with feathers when I find it. Does anyone have any idea if this is a normal laying behavior or is she just odd? I haven't seen any other posts describing this kind of behavior. Could she be marking her eggs??? Any ideas??
