Oh my....
The pullets were making an awful noise back in the run. They've only been out there a few days. A big hawk was sitting by the run, inches from the wire. Ran out and shooed him off. Found one of our girls dead by the wire. The hawk had gotten its beak through the chicken wire and apparently pecked an inquisitive pullet. I usually like telling my wife "I told you so", but in this case, I didn't much care for the job. But now she's taking seriously my original suggestion to wrap the bottom two or three feet of the run in hardware cloth.
