I have several birds that have gotten too cold earlier in Dec.....record cold and snow where it does not happen, one hen got a foot literally frozen...she got stuck under the coop...when I counted fluffy butts...noticed one missing and found her...she has resided in the house for about 2 1/2 weeks...she is even laying eggs. Her foot (the toes are curled up, blisters scabbed over, the color is about normal now...no blackness at all, swelling down, she bears weight but her foot is curled up....any ideas on what I can do for her. The second one the scales on her legs appear rough and she had some blisters...again she eats well and lays eggs. The frozen foot bird is Snow White...a white leghorn. mary
