You can’t really tell whether they are male or female from their size. Some females can be quite big. I think they tend to get bigger as they get older, although, having said that some always seem to stay on the small side.
Just to illustrate how contrary hedgehogs can be sometimes – I didn’t have any hog visitors last night until 11.15 and then, judging from the Cams it was a very quiet night. That’ll teach me to say the first one usually arrives at 8.50!
I find it very worrying when that happens, especially now those ghastly traps are around, but it does, occasionally. Just hope they arrive as usual tonight.
