Lost four, month old chicks, in with banty mother, three survived but the mother is also gone. Space under coop the 2" side of a 2x4 which I had blocked with a 2x4 so the babies would not get out from under. Something moved the board, got under that small space and inside coop, there was a puncture wound in each chicks head about the size of a 22 caliber bullet, no other wounds or parts missing just dead chicks. One in the nesting box, two in one corner, one in another corner. Mom is nowhere to be found. Is there a farmet that sucks blood and leaves the entire body??? Would it have taken the momma away as well?? Sad in California, she was my favorite chicken, and raised many babies in that coop and I have never seen anything like it in my 30 years of raising backyardchickens !! Any response would be appreciated.
