How many hedgehogs are there in Lanefoot garden? And why do they bully each other?

We never knew until Martin and Emma and Stanley and Robert gave us a wildlife camera for Christmas – thanks. I didn’t realise that it took such good pictures in the semi dark so I had waited, but wow!

All seems quiet and peaceful until after 2mins something is happening, but is it friendly, who is the dominant one, what happens when big mamma turns up, and was the mouse hiding behind them all that time?
