Wasn't sure where to put this one. I thought we lost a hen, in searching for her I found she has been nesting under our shed, and I was surprised to find a dozen eggs there. We thought we had a hen or two holding out on us. I guess not. SOOO the question is, how long are they good for? (yes this is our first set of backyard hens). I live in Vriginai and the temps have been anywhere from low 20s to low to mid 70s. Any advice?
