Same happened to me I was running around people's garden looking for her..I gave up hope after 4 days of setting traps and no luck on the 5 day when I came home there she was walking around the garden
My Jill that I got this year is hyper jumping and rolling over but when I take her out she is not hyper she just does her work and she is the best ferret I have ever had
give him a drink of milk for a cupple of days and then put milk on your hand and then he should lick the milk of your hand instade of him biting you .... it worked for my jill
