Just got my first ever mail-order chicks. Ten layers, fifteen Cornish Rocks. Hatched last Friday (this bein' Tuesday). Layers are all fine. Noticed last evenin' that one of the meat birds had a big pink spot under her tail. Gave a look, and at the time it could have been as simple as her havin' dumped her rump into the waterer. Today, though, the spot is dry and larger. She's one of the larger, better thrivin' of the bunch, and none of 'em show any sign of peckin' that might be causing this. If still present tomorrow, I'm thinkin about maybe slappin' a little Neosporin over the area Any thoughts about what it might be or how to address it?
