yesterday I planted some carrot seeds, using the compost in the trench method as our soil is newly dug and not very tilth-like yet. When I went to the lottie today I found a neat hole dug in the row, about the size of an apple. being a newbie I was puzzled, but so was my very experienced partner. He had just been showing me fox excrement, so we knew we'd had a fox in, but it was a bit small for a fox to dig, and for what reason? Also, we do get rabbits, but again, nothing green showed any sign of being nibbled, and so there didn't seem any reason why a rabbit would dig a hole to get at a carrot seed. He thought it was too big and tidy a hole to have been a blackbird. Any ideas?
