so one of our chicks is really beefy, (in case it might be breed related but i dunno) but he is growing in 'knee' feathers, I got a blurry pic but if you look close you can see, i have had chicks MANY times before, hes gonna be 2 weeks on valentines, and i have never seen a chicken with feathers like this, not only are they growing in at a young age they are like, well heres the pic
the feathers sproting out are the bending part of his leg
