3 days ago our sapphire gem layed her first egg in the corner of the coop. Two days later she layed a translucent one while out free ranging. Then this morning we checked the coop and there was shell and egg yolk in the corner like someone ate it. She won't leave the spot now and seems really anxious. She is nesting there in the corner all puffed up. So I have multiple questions. Should I be super concerned that the egg was eaten? How do I get her to go in the nesting box? And can hens go broody this early (she is 20 weeks)?
