You can, but I wouldn't--Well, I never, ever, ever, never will again! Using pine pellets for bedding is less dusty then shavings, but it's still horrible. It's not so much keeping the brooder clean that is the problem, it's the amount of dust and dander that that many chicks will create. Last time I did it we only had six and my son wanted to brood them in his room so he could handle them a lot so they'd be friendly. It was a good idea for friendly chicks, but a huge dusty mess for everything else. I saw a previous poster said that they did it on wire and that may work better, I've never tried it but at least it would cut down on the dust from the bedding though you'll still have to deal with the dander.
Do you have a garage or other secure outbuilding that you could brood them in instead? If you get them now they'll start laying first thing in the spring so that is a major + in my opinion.
