I have a broody hen that has been sitting for over a month. It is a school pet that I am taking care of, and I can only go every 2-3 days, so I take eggs and clean but the other hens keep laying for her to sit on! There are 4 hens all together, and this one is the only broody one, and she'll sit whether there are eggs or not. There is a section of the coop that is separate from the rest that I could put her in. How long can I keep her separate before there are reintegration issues? And how long might it take til she figures out that there are no eggs to sit on?
