All 3 are 6 weeks old. Thank you

I'll let someone else comment on the breeds and genders.
Those birds are sick.
Where did you get them?
What are they eating?
What does their poop look like?
How is their breathing?

ETA: if you don't have Corid, go to your nearest farm store and get it and start them on it ASAP. I would direct drench each bird once daily for 3 to 5 days with 1/8 tsp of straight Corid if you get the 9.6% liquid.
That will cover them if it's coccidiosis but answering the other questions will help hone in on why they look like they do.

Agreed. They are quite sick. First thing I noticed.

All appear to be mixed breeds and look like pullets for now. Focus on getting them well and post update pics then.

I have to agree. Those birds look ill. I think you should post pictures and symptoms in the medical emergencies section to find out what can be done for them. Here's the link: https://www.backyardchickens.com/forums/emergencies-diseases-injuries-and-cures.10/
