A few weeks ago it snowed and got really cold. We have 5 month old pullets, and the one that has feathered feet (cochin/RIR/New Hampshire Red mix) has gotten cold, simi frozen feet. We've been taking her outside during the day, and in by night; her feet just don't seem to be getting any better. If i rub her feet will it help? She just waddles around and can't get to the food or water fast enough because the other birds beat her to it. I'm worryed there's something wrong...is there anything I can do for her?
