Events for the festival began on Monday, with Thursday's list of activities including window painting on downtown's Main Street.
Other things to look forward to include an art show, live music, food and of course the games and rides of the carnival.
The proceeds go right back into the community.
"My favorite part is after this is over we go back to our meetings in September [and] we just start giving this money away to Pine Tree Camp, Camp Capella. We give out scholarships to the schools," Mike Platt, president of the Greater Pittsfield Kiwanis, said Thursday.
Saturday's Egg Festival activities will kick off with the famous big parade. The lineup will begin at 8 a.m. and the parade steps off at 9:15 a.m.
