Advice please?

I had one 1 out of my 2 chicks that were 7 weeks old pass away last night….will it be ok if I put the other one I have in with my two 1 week old chicks? I have them together now as of about 30 minutes ago..being supervised and the 7 week old is super chill and is kind of mothering the littles? There dad is a grizzled bantam so even at 7 weeks it’s still pretty small.

I would keep an eye on them. I successfully did that last year, the male was older and the younger chicks were female.

However do you know why the other chick died, strange at 7 weeks? I wouldn't introduce it if something was wrong with the other chick.
