My amaracauna chick I just got from Big R has pasty butt, i wipe her butt everyday and put olive oil on it but i just recently discovered what i thought was just poop stuck to her below her vent. I took tweezers and pullled it out. Something was growing inside of her and there is now a small hole. Ive never seen this before. I put antibiotic ointment on it just in case it could get infected. She drinks water and eats and acts fine. It reminded me of a blackhead or something like that. She didnt make a peep so it didnt hurt her. But im afraid i left remnants of something bad. Please help im worried. Ill attach close up pictures.
