This is my first time experiencing my ball python shed and she didn't have the best shed ever I tried to keep the humidity to 50-65% but it kept dropping. I didn't want the substrate to grow bacteria, but I didn't know what to do back then I'm sorry for my ignorance, I'm still new to owning a ball python and this is my first time seeing her shed. She shed in pieces but she still has the dead skin on her head. (She also has one retained eye cap.) What can I do to remove that? I gently wiped a damp paper towel on her head and she flinched away. Do I have to keep doing this or should I try something else? Is this something they can shed on their own or do I have to assist?
