Old hens and poor circulation?

[TreeHugger]

I'm in the Midwest and we've only had a few weeks of cold 15-20 degrees and no snow where I'm located. Yesterday I noticed one of my old silkie hens walking weird and her toes were frozen. This morning one of my other older silkie hens was dead. Both of her feet had suffered severe frostbite - they looked bad. (I've had both girls about 8 years) My coops are off the ground, insulated and have deep pine shavings. Both of these girls roosted on the floor of the coops so there was no cold air getting to their feet at night. They did go outside into the chicken yard though. Does anyone have any suggestions or issues handling older hens and the cold? I've got about 8 silkies that are 8-10 years old and the winter has just started.

So sorry about your loss but I would give them a heat lamp near the ground on a small place in the coop where they sleep. Good luck!
