Hi, I hope you can help with some much needed advice, I have a silver jill who recently had a litter of 4 kits, two have gone to live with my friend and two (one hob and one jill) are staying with me. The kits are 9 weeks old and still in with the mother, at what age would it be suitable to introduce them to the father (who until a week before birth was housed with the mother). Any advice would be greatly appreciated.
