You know, one of the refreshing things about this forum is that in the middle of it all someone will end up asking about something as perfect as rabbit droppings. It's not that it's rabbits or that it's droppings that make it perfect. It's the fact that the person has an excess and doesn't know what to do with them. The perfect problem. I wish it were my problem.
I think you should send them to me. Simple solution.
Alternatively, i reckon get 'em dug into the soil. For beds like cucurbits(pumpkin, squash, cucumber etc) you won't cause any problems. Dig 'em in and
plant your stuff. Those
plants love manure. Older stuff, use for brassicas. (Cabbage, broccolli, cauliflower etc. They like plenty of nitrogen but don't like the heat of breaking down bulk organic matter. Anything that's well composted use for the rest. Tomatoes,
peppers and other solanums such as
potatoes. Sweetcorn. Perennials like asparagus, herbs too. Load 'em up with the older stuff.
Or just send the rabbit crap to me!!!!
