This last cold snap reduced my Peayoungsters quite a bit. My losses include my 2 Opal hens, a Silver Pied and Purple Silver Pied cock, a black shoulder male, a white hen and then a Mink snuck in a rabbit hole into one of the pens and took the head off my Bronze hen. I now have no Opal, no Bronze and no Silver Pied males. All were lost during the nights when temps dipped below zero. I do however still have, IB, BS, Purple and Purple BS, a Silver Pied hen, white and a Cameo pied hen. My heart is broken. We thought they were pretty well protected and old enough for no heat but it was just too cold for my hatch from Florida eggs. I now have lamps in each of the pens as I did not lose any from the pen that still had a light heat source. All of these birds were over 6 months old.
