Mixing three week old chicks with 2 day old chicks?

[Jose21]

What do people out there think about having three-week old chicks (just two of them and they are pretty tame) that we have hatched together in a brooder with a couple of two-day old chicks? Problems?

That'll work, I should think. As long as they have room enough to "avoid" each other a bit.

I think it will work, too. Just watch at first for some agression/excessive pecking....
