Hey Guardian, As you are aware that they're very vulnerable at this age. If you keep them out doors as to a barn, that there a predators that can smell them in the area due to there sent. This is especially true for bears. Sadly this is a dream come true for the taking by coyotes, fox's, even a wolverine's and badgers, will make an attempt if it is big enough. Also that badgers are diggers and will tunnel under a fence line.
Cougars, mountain lions, as well as bobcats, will have no problem jumping that fence and taking them for food. Out here there are many free range animals grazing the grasses that wear bells for making there movements known. Owners can better track them if they can't be seen or needed to be rounded up. But i like your approach as to the hassle and exposure to the by product's of a weeded whacker, the enviorment and as well as to yourself. Also there Cute as botton ;D though.
