depends on breed, do you have any idea what she may be? yes they can be, though clipping a wing can help off balance them sometimes it doesn't help all that much. she will prob lay between the 20-26 week mark, at first it will be small eggs and there may be large gaps of time in between receiving eggs, after a few months she should settle into a routine and you should get 4-6 eggs a week breed dependent. I hope you have some high protein food and grit available as it will be needed for the eggs, without it the hen will have to take calcium from her bones to make the eggs which can lead to brittle bones
