Hi. I'm not new to chickens but have never seen this. I have a chick with a bump by her left leg. She acts healthy otherwise. Any ideas? I took a pic while I was washing her. She needs to be cleaned twice a day to prevent pasty butt. You can see her vent is clear and the weird thing is on the right. I have since cleaned the rest of the poop off. But I took the pic at a moment when I thought it could best be seen.
