That's a good idea too. Puppy pee-pads that is.
I'm more of a recycling type person. Use something over and over again ya know? So the shelf liners will work great for me since you can wash them and reuse them. (I've got clothes still that I have maintained for 10 years or more and still wear lol). They also seem to provide a way to get the chicks off the floor. The brooder I'm setting up is acctually a small shed with a concrete floor that I put a solid peice of bathroom tile-type panel over. When we built our new building I decided to use the old shed as a brooding building. So I got the light set up now, just ordered 35 square feet of pink shelf liner and now all I need is the chicks and feed. ( I don't buy feed till I get the chicks right? So it stays fresh longer. )
