I was looking at my chicks tonight and i found on ones toes little lumps of hard brwon stuff. I have no idea what it is. At first i thought it was poop or food stuck. Then i tried to wipe it and its actually hard and stuck on. Im scared to try and actually take it off because i dont know what it is and i couldnt find anything about it. I attached pics so if anyone can help me please i have no idea what it is if its a disease. It actually clinks on the counter top thats how hard it is like a rock. Please help!!
