I have an Ameraucana that has just recently started laying eggs. Two days ago, in fact. On the eggs (blue-green in color), I have found small clumps of little round balls (also blue-green in color) in one or more places on the egg. They look like they could be nits except that their color exactly matches the egg. There are 3 or more 'layers' and they're bunched up together. They can easily be scraped off with a fingernail and don't leave a residue. I might also point out that of the other 12 laying hens, none have produced an egg with this phenomenon. Also, I have not yet had a chance to check the chicken directly for lice, but we have not had an 'outbreak' or any indication of lice on any of the other chickens. I'll post a picture as soon as I can, but thought maybe somebody has seen something like this before. A cursory search of the internet provided little. Thanks!
