How can you breed if you don't have a hob spayin a young animal a small one is a tricky op I personally wouldn't spay a jill till she's a few years old , but it's up to you , Christmas is in December and if you do they won't he seing much action for a good while after a major op like that , oh and them jills are 9 weeks old fieldy , I would just enjoy them mate and get them brought out of season the first year and if you still feel strongly the next winter get them done hope this helps , not long now fieldy
