Marlow get a couple 1X4s and tack to the inside, and then put a layer of plastic at the very bottom to lap over the 1X4s. that way you can easily clean out shavings without them kicking much if any out, and if you need to or can - you can just pull up plastic and throw away in a bunch (like those kitty litter liner thingies?)
I did something very similar for a big outdoor grow out last year when it was still quite cold in March with 20+ babies
Thank you for that suggestion! Definately sounds like a good idea. The only issue we have with the brooder (besides the shavings escaping issue) is we didn't make the door on top very big and it becomes a problem when it comes time to change the bedding. It also makes it fun to try to catch chicks when they want to run to the corners! I may have to see if DH will cut a couple extra doors or make the current door bigger.
