In all my years of keeping radixes I have never been attacked by one. Feeding response bites, yes but I've never had one come after me at a non-feeding time.
That all changed this morning. This young female has been on the ranch since birth. She has always been a good eater and had a pleasant demeanor. I opened the enclosure this morning and stuck my hand under one of the hides, only to get tagged, repeatedly. I pulled my hand out and continued to get hit. These were open mouth shots. My arm was well inside this 6 foot enclosure and as I pulled my hand out she followed me out. I got my hand and body out of the enclosure and she leaped out towards me. I had had enough and grabbed her. She twisted around and grabbed a mouthful of my hand. She held on for a few minutes. She finally deflated and released her bite. I put her back in(got a photo) and she went under her hide as if nothing ever happened. I must have startled her and she was making a point.
Point taken, I will announce myself the next time I enter that enclosure.
