I came home from work last night and from my driveway I could hear a chicken making noise. My son went to investigate and found that the mother hen was on the wrong side of the fence and couldn't get back into the yard (somehow she manages to get out but not back in). He got her back in the yard and told me that another one of the chicks was missing. I waited until it got dark to be sure. It didn't show up. So now we're down to two.
