Hi. I'm new at this too and am impatiently waiting for my 10 new chicks. (Coming May 16) I am setting up a plastic kiddie pool in our garage with heat lamp, etc. I put newspaper down first and then will add the pine shavings on top. At least maybe for the first two weeks? Then maybe switching to sand might be a good idea? Like you say, it would make cleaning easier with a kitty litter scoop. Will it hurt them to eat the sand? Are they still on chick starter?
I also read on BYC to maybe put a roll of chicken wire around the pool too so as they grow they won't leap out. That might be a good idea too. I'll post a pic once I have it set up and see what everybody thinks as I have never raised chicks before.
