Wow there seems to be a lot of experts here. I have 4 Jills, 1 Jill 2 days from giving birth , 2 Jills have had one of my vas hobs over them and the last Jill is not in season yet. I have Kept ferrets for 26 years and i have seen Jills in season in january. I dont belive in breeding a Jill twice a year but i am not gonna give the guy crap for what he does. So all the best to you with your kits and dont listen to the smart mouths because if they are looked after properly thats the main thing.
