Usually there are chicks at Agway distrib in Hatfield - half hour north from you. Tha's in spring but still worth a trip right now - If you go to the feed stores - Easthampton Feed, Greefield Farmers' Exchange, Amherst Farmers Supply, and Hatfield Feed, you usually can find offers on the bulletin boards. Also if you want started pulets Murray McMurray is selling Red Stars and Black Stars - crazy layers - right now at 17 weeks, almost point of lay. With shipping, might be expensive - I've never ordered grown birds, but people do it all the time and then you'd be done and getting those eggs right away.
Last, the farm section of Western Mass Craig's List is pretty decent. You could try Northern CT/Hartford area CL too. Don't know much about feed stores etc as I'm a ways north, but somebody on CL down there would know. . .
Yay for chickens in Spfld!
best of luck!
