This is my second year rasing chicks but this is the first time I've had this happen. One of my chicks has a little less feathers on her butt than normal. Now it's nothing to crazy just a little bit more pink showing than the other chicks. I'm wondering if this is normal or if I should be worried. She is at that "ugly duckling" stage where they are growing in real feathers. She's the only one having this issue out of 7 other chicks. Thanks!
