I have eight hens four Artsrolops and four Buff Orpingtons. I am getting an average of about 4 eggs a day but I would like to know if any of the hens arent laying or aren't laying much. I was thinking of locking each one by herself in a rabbit cage that is 2'x4'x2' for a week and see what she lays. But then I have to worry about reintegration of the hen, dont I? How do I tell which chickens are laying eggs and how many eggs?
