I've got 12 hens (and 1 rooster), just passed their 1st birthday and have just started laying again in the last few weeks. To save eggs to stick under a broody hen - how do I do that? Do I refrigerate them or leave them out? I'm afraid to leave them in the coop because we've had problems with snakes. One of the hens went broody last summer - is she likely to do it again? Thanks!
