Crippled Chicken

My Cockerel was in the coop today when i noticed he was standing on his foot strangely, one of his claws (toes) was bent underneath the rest of his foot. I made him walk on and he was fine to walk on it and didn’t limp or seem in any pain! Should i be concerned or is this normal?

Thanks. 

My chickens often stand one one leg and have the toes on the other foot rolled under as if they were trying to stand on the top of their foot.

I guess it's just normal because there is nothing wrong with them... perhaps just like us shifting our weight onto a hip?

Thanks for all the help.
