This is the first real rainy day since I got my chickens (that is when it's been cold out). My chickens free range in my yard all day. They have three dry options to hang out and forage in. They are currently in the middle of my yard getting soaked. Do I need to lock them up.? Are they dry underneath? Do I need to catch them and dry them tonight? They look miserable but can't be persuaded to go under the dry shelter. Help
