I have 5 chickens, and one of those chickens is a broody hen. Now we don't have a cockerel, so there will be no chicks. Now i have been told to put Omelette (the hen) in a "sin bin" for 3-5 days, my question is does she have to stay in the "sin bin" over night too or can she go back into the coop with the other four hens or does she have to stay separated for the full 3-5 days?
