A friend of mine is have problems with a buck she has. He gets very excited at the sight of my friend putting him in his cage after bringing him put for a while. This ends in the her getting scratches and punctures in the skin enough to make her bleed as the rabbit squirms and kick (Silver Fox sized rabbit). Her hands, stomach, and chest are scratched up and she does not know what to do. Her other rabbit is very calm and unlike this buck. I have not had this problem before nor have I seen the buck get excited but she did show me her scratches she got from this buck. I don't know how I can help her but a few things did pop in my mind... Are his nails too long? Is she provoking the behavior by carrying him in an uncomfortable manner? Does the buck have a behavioral issue in the first place?
... the best and easiest way to handle all rabbits with the absolute minimum risk of being scratched is to grab them firmly by their ears together with the loose skin on the back of the neck then with the other hand place your hand on it's rump and rock them backwards / lift and rest them up onto your palm of your hand to carry while still firmly holding onto it's ears/ skin . Then when you want to release them , place them on their back ends down, then rock them forward , then release your hold from the ears/ back skin in a smooth quick motion away from you.
