Sexing guinea pigs is a little trickier than alpacas

A couple of months ago for young Edward's  birthday his Gran bought two female Guinea pigs for him. Unfortunately three weeks ago both females gave birth to five wee ones. Apparently Guinea pigs can breed at three weeks so suddenly we have five iincestouos offspring to find homes for. 

Today was week three for the little ones and this morning Shirley decides we have to sex them and separate boys and girls immediately  be on the safe side. So before we leave for Germany to judge alpacas we are sexing Guinea Pigs. As you do.

 The one below protruding is a male. The one not protruding above is a female. Obvious, when you know but tricky to apply the right amount of pressure to facilitate protruding. All this over ones Cornflakes. There's never a dull moment at TOFT alpacas. At least they won't get to bonk their mothers and sisters while we are away!
