I have two white Leghorn chicks that I hatched out from eggs from my own hens. As far as I know the hens are pure breeds - they came from a local farmer who kept different breeds in separate pens as he sold them as breeding trios. I got some of his older hens for free last year and I sneakily set the first few eggs they laid, thinking they should still be fertile - and they were! Five birds for the price of three. Oh, yeah, they were free in the first place! D'oh... Anyway one of the chicks is completely pure white as expected but the other one feathered up with a single dark grey feather. Now at approx 5 months old it has lost that one dark feather but it has got some tiny dark flecks on a few of its feathers, and it also has a small dark grey spot on its otherwise correct pale pink legs. Is this just something that happens sometimes with Leghorns? Do the different colours not always breed true? Or is this birdie's daddy not who we all thought it was?
