We went out yesterday with the ferrets and a goshawk. Ferreted a decent sized warren. First set of holes snow on the ground it become obvious that my ferret(had a locator on) was on a rabbit. As soon as i started to dig, it moved (due to the frozen ground i mate quite a bit of noise). A few minutes later, the other ferret which was also down the hole bolted the rabbit and chased it out the hole, and rather than having a sniff around like i have noticed they usually do, it ran straight back in the hole like it was spooked.
It never come back out. We thought maybe it was on another rabbit,
