So my quail have been laying eggs for a few months now and I go out to find this egg and another one that was solid sky blue. Anyone know the problem? they get oyster shells and 22% protein so is there some other factor? I got one blue egg a few weeks ago but it was only the one so I chalked it up to them getting use to laying but now I have two weird ones... I don't know if you can tell, but the bottom is solid blue too it just has a broad white stripe going horizontally across it.
