Got a hob gave to me last september, biggest ferret I have ever seen, for the first 3 weeks he would not come out of the nesting box, he was quiet in the box when he did eventually come out, sometimes when you lifted him he was ok, but other times he would go completely wild, I kept him to April this year tried everything but just could not trust him, by the way the man that gave him to me caught him wandering around a farm yard, unfortunately had to put him down, but good luck with your jill.
