We had 2 wonderful EE hens that we found dead 2days in a row. Something ate their head and feet and tried to make a nest out of the body...they were in a space near impossible for most animals to get into(no fox, raccoon, etc). It was just strange. Well, our dogs caught a weasel that weekend and we have had no more losses since(2wks). I see many people have problems with "mystery predators"(and we did too until the dogs brought their catch). We never did figure out how they got into the coop or how they got the hens out...we have since taken the whole coop apart and reassembled since we couldn't find a problem. Hopefully that will ensure the problem does not continue should another weasel find its way onto our property. This was our second experience with wild animal death, we lost one in spring to a hawk while we were out with the babies(3mos)-not even 3' away...another very sad day...worse because we saw it, but better because we weren't as attached as we were with the weasel attack...chicken death is ALWAYS hard.
