It has had an extremely bad (broken?) third leg which has been very swollen for about a week and a half now. End of Litter Aug 30 The last of the litter was killed today, it seemed to have recovered from its broken leg and was in fine health but the project will close in a couple of days and therefore the lemming was killed and skin * nest had been disturbed earlier in the day by someone wanting to see the young - this may have caused the death indirectly.
