Are My Chickens Frostbitten?

[Prieto1399]

New chicken owner here! I'm worried that my chickens may be frostbitten, and so any advice would be great. I'm attaching pictures of my lovely ladies. I live in Mid-Michigan, so we've been getting some snow and cold weather lately. I was told that I don't really need to do much for my chickens besides keep their water heated for them, as they are cold hardy breeds (2 silver laced wyandottes and 2 sapphire sky), but I'm worried that they are frostbitten. What do you think?

Look fine to me.

No. They look fine. The greyish scales on their toes and feet are just their normal coloring.
Frostbite will kill the tissue starting the the points furthest from the body, the tips of the combs/wattles and their toes. Unless a foot or something got wet in frigid weather.
You need to keep all water sources out of the coop and have plenty of draft free ventilation to allow moist air to leave the coop at night. They will also do well with a wind protected area with some litter on the ground so they can scratch around outside during the day.
