I don't use that lining! That stuffs get chemical reaction....I use paper on the bottom to line the base of the brooder then I put bedding on top and I like using shredded wood made by kaytee, the ONLY one I will use, all the other ones are too rough. You can make your own brooder by using a 10g aquarium and use the reflectors with clamp on light and use 60w bulb, that would keep them warm too. IF they're really young you would want to use two clamp on light and I usually put a cup of water in there for humidity. As they mature you can remove one of the light and cover that side with a towel. It's something I've been using for many years.
