Different aged chicks in a brooder

[RooBeeC]

Do you guys think it would be a problem to mix few day old ( like 3-4 days old) chicks with 2 week old chicks? There is enough room for the bigger chicks to walk away from the heat lamp.

Maybe not? It depends on the behavior of the older chicks, so be prepared for a second brooder if the littles get picked on too much.
