im not a newbee on chickens but some stranger gave me a trio of white silkies free. its summer now, but do i need to do any thing when winter comes? but also, i noticed the toes were longer than usual, and now they are shorter and the roosters toes are bleeding. i suspect its sence they are grinding away on concrete, but is this to worry? please help! if you have info of cordon pls post on last page.
