We have 4 4-week old chicks in the house with us...two of them belong to our 5yo son and 2yo daughter. Today we decided to let them stretch their legs in the run. Apparently our daughter's chick "Pink" had a small enough head to stick through the wire and our beagle cross killed her. I feel like a terrible chick mommy and I feel just horrible for our daughter. Needless to say, we'll be covering the current fencing with hardware cloth.
