I have bantam who has been sitting on her two eggs for 2 weeks now. When she gets up to go eat the other hens lay eggs in her nest. I think one of the other hens eggs bumped into her egg and made a small crack in side. I candled it and its all dark with air pocket on bottom of egg. Will this crack hurt the chick inside? I was told I could melt some wax and seal the crack? Any information you could give me would be a great help.
