Are you planning on putting pine shavings in there anytime soon, it's so much easyer that way, I could never image having that many week olds on PT's you must have to change it 20 times a day !!
Actually I never use pine shavings, I just don't think it is good for them. So far I am changing the papertowels just twice a day. Next week sometime however they will move to a brooder outdoors where they will have quite a bit more room and they will have hay for bedding. It is quite a few for this brooder but they will be moved soon.
