Last Friday I gave away a Buff Orp who only laid soft shelled eggs (I tried everything, to no avail). On the same day, I brought home a seven month old Plymouth Rock and added her to my backyard flock of two (now, three). She laid her first egg in the coop today...but my other two pullets who were quite regular haven't laid since Friday! Could they really be that stressed out about losing one chicken and getting a new "friend" that they aren't laying??! I even gave them chopped steak tonight trying to get back in their good graces.
