All the ferrets I have ever owned have done this on the first few trips.
My 2nd year albino jill played on her first few trips now shes brilliant!
Her offspring went out last Sun for her first working day and was exactly the same.
Once they get used to working a burrow and have their first 'chase' I recon they change.
Both mum and her young, a hob and jill, are very tame in their hutch and run have never bitten either me or the kids! Who wants a biting ferret!
