Recently when candling eggs I was selling for hatching, I noticed some of my crested cream legbar eggs had air bubbles in them. The bubbles move to the top of the egg as it is rotated. So far I found about four eggs that have these bubbles. The eggs are from my hens and have not been dropped or mishandled. I am assuming they are all from the same hen, but I'm not certain since I have several legbars that lay very similar eggs. Has anyone seen eggs with air bubbles before? Historically I have had a very low hatch success with the legbar eggs. I'm beginning to think the bubbles might be part of the problem. None of the eggs from my other hens have bubbles them. Do you think the bubbles in the eggs would prevent the chicks from developing normally and hatching?
