Chick ID help

[Chicken noobie]

So it’s our first time raising chicks and we’re only 4 weeks in. We bought them at the local tractor supply and the guy working there didn’t know what kind he had. So I wanted to see if anyone could help us figure out what kind of chicks our 4 hens(hopefully) are! I think we have two Rhode Island reds, one Australorp, and I just can’t figure out the white one. This is all just a guess based on some google searches. Any help would be great!

Rhode island reds, Delaware and Australorp. Generally you can tell sex by 5-6 weeks as males will get pink combs by than. So give them another week or two. They look like pullets for now.
