I had two of my favorite hens slaughtered by a break in, either by neighbors dog or coyote. These two were the oldest of my flock and best layers. I have about 10 more spring pullets that laying too and one EE roo. The older hens layed larger darker colored eggs, (golden laced and a Maran) well identifiable. After the slaughter I pulled all of their eggs which were refrigerated in hopes of hatching them, in addition to a few of the pullets.....just in case. I allowed them to warm to room temp before placing in my incubator. They were not scheduled to hatch until Monday. They all have started hatching 2-3 days early. I have always had eggs hatch on time or later, never early. Since these are all refrigerator eggs, my first, is this a good sign/. So far I have 9 out, and three more pipping.
