Noticed on two fields next to each other - one has wheat - one has been cut for silage, all in the "hot spots" there are considerable amounts of droppings.
The black, newer ones are obvious, but as mentioned there are lighter, straw coloured ones in copious amounts. So does this mean there are lots of rabbits or just a few and the droppings have built up ?
How long do they take to biodegrade, is there any way of ageing them type of thing ?
