Hi erin, still thinking about you
There are several different weasels, the smallest is the least weasel, about the size of a large chipmunk. They go up to about ferret size. All are cabable of killing chickens.
Although a rooster is great at sounding the alarm, they are not equipped either...
Erinlee, that is too bad, how sad you must be.
Come over and visit the Michigan thread sometimes, lots of nice people there to commiserate and help you out
