I have used my brooder many times just this year. I always try to build to reuse, but that may be of limited use to you if you aren’t planning on more chicks in the future. My brooder doesn’t have doors, just openings. I use bricks to block them off when needed. A proper door and reuse is up to you.
I would just use up the starter you have. The rest of your chickens are fine on it, then switch to the grower when you run out. I never throw food out because someone outgrew it and it doesn’t keep as long as you might think.
