Info on flooring for chicks: Do not put any young chicks or chickens with leg problems on any kind of slick, painful or hard surface! This includes newspaper, cardboard, linoleum, concrete, flooring with sharp points, etc. Small wire mesh can provide traction as a floor, but gives chicks a higher risk of getting chick leg problems from getting bruised and hurt when stumbling around trying to walk. Don't use hay or other materials the bird is likely to trip on. Good Flooring is needed to provide adequate traction and cushioning, and decent sanitation. It is critical for ALL newly hatched baby chicks, so they do not slip while learning to stand, and develop leg problems. Appropriate flooring keeps a chick from slipping and developing Splayed Leg (where the chick turns one or both legs out crookedly to the side & has a hard time walking), and helps prevent bruises, scrapes & bone injuries. For very young chicks: 1 to 2 inches of pine shavings with paper towels laid over the top (Paper towels keep chicks from eating shavings while they're trying to figure out what they should and should not eat the first few days). Bumpy, rubbery kitchen shelf liner is also good. A soft washcloth is ideal for a lonely chick to snuggle next to. For healthy sanitation, frequently change out paper towels or clean (& thoroughly dry) washable flooring. For older chicks: 1 1/2 to 2 inches of pine shavings. Clean dirt also works. Wood floor is alright if it isn't too slick, and there are places with bedding for resting. For sanitation: Change out shavings as they become dirty, or sprinkle a layer of fresh shavings over top. There is also a drawing of Splay Leg Hobbles made from tape on the Poultry Podiatry page on the website linked in my sig. I hope you have fun with your crew of chicks!
