After having had a lovely little cuddle with the babies this evening, I have revised the dumbo count.  I now think we have 4, still all girls though!

Current numbers;
2 x Champagne bucks
1 x SF bucks
3 x Champagne does
1 x Champagne dumbo doe
3 x SF dumbo does

Will check again tomorrow and see if I come up with the same answer…..
