My hen "mother" has been a basket case ever since she has gone broody and she raised some chicks. Her babies are grown now and every since Mother has seem a little off her rocker. She was fine for a while and acted norm, laying eggs ect. In the last two months it's like she is "kinda" broody. She makes mother noises, doesn't lay, plucked her chest, is moody ect. Basically all the symptoms of being broody EXCEPT setting eggs. She has also lost some weight. Is she OK, but just a little Koo Koo, or is there something I should do?
