Two out of my ten Silkie 3 week olds have pasty butt that recurs every day or two. I have given them baths only twice since I felt they got too stressed out by it. Also this caused a speck of blood to occur (even though I washed gently with a cloth) and I was horrified. The poo is not sticking because of bottom fluff getting in the way- they look the same on their bottoms as my other Silkies. It fall off by itself after a few days, but then the next day or so it is back. I painted them with rooster booster pick no more at the beginning since they were picking at each other's behinds. This worked immediately, and I have not seen any more picking. *Both of these chicks are a LOT smaller than the other eight Silkies from the same hatchery shipment. Also they are clumsy on their feet, and when we had a heat wave, I found one flopped on its side like it couldn't get up. I brought it inside, it perked up, and it hasn't had that happen again. I am wondering if I could be looking at failure to thrive, maybe a mild case of it? They are starting to feather out, but at a much slower rate than the other ones. Has anyone had this happen and still the little ones survived? These are my BABIES!!!!
