Hen with a cold foot

[27seekup40]

Hi there. My Production Red hen's right foot and leg is pinkish and cold, yet the left foot is warm. A few scales on her leg were also slightly lifted, so I sprayed Poultry Protector. Later, I used a warm paper towel on her foot. Has anyone else experienced this with their chickens? I have attached a photo for reference.
Thank you.

Do you see any injury in the leg, or something wrapped around the leg? Do both legs look straight? Is she limping?

No visible injury or anything wrapped around her leg to cause a loss of circulation. Yes, both legs are straight and no limping. Before I locked the coop for the night I felt both of her feet and they were warm but I don't know if it's because she was laying on them for a bit before I got to her. I will check her feet/legs in the morning.
Thank you for taking the time to reply to my question.

Let us know if there is any change.

Let us know if there is any change.

Scarlet's right foot was pinkish on Sunday. I checked all the way up her leg and found nothing suspicious. I ran her feet under warm water and washed them to check for injury but found nothing. Today both of her feet are pinkish. When I put her in the coop this evening her feet felt warm so I think I overreacted thinking something was wrong.
Thank you for your concern.
