I was out in the yard and noticed the smallest leghorn I have (8-9 months old) has these black dots all over both of her legs. We picked her up and they are not raised and they kinda look like bruises but am not really sure and would like yalls take on the matter as this is my first year with a flock. And I have done lots of research but haven't found anything that looks like this and she the only one that has it. She also one of the higher ranking hens in the flock of 22 hens ranging from 9 months old to 2 months old. Thanks for your help!!
