I went into my barn today and let my chickens out to free range. when i came back to put them in for the night I found 2 of my chickens dead ( chest ripped open only guts gone) and my rooster completely missing annnd two of my chickens badly injured with only fang marks on their lower chest and blood over their chests. I then found my rooster hidden in a noke in the barn with once again no marks on his body except for two "fang" marks on his chest. I've been told may be a weasel but would like to get more opinions...what predator would prefer only to take their blood? thankfully my two hens have made it thru so far I have removed them from the flock due to the others peckin at them and have been babying them...but what your opinion as to wut is gettin my chickens?????
