Can a young hen adopt 2 weeks old baby chicks?

[Nounoushe]

Sorry if my question seems stupid im new to chickens completely , so i have young sex-links and longhorns not sure yet if all females or rooster in the group... They're about 2 months old. I just got another batch of chicks maybe 10 days ago from Tractor Supply, And i noticed one chick is chirping and desperately trying to go under the other bigger chicks. I feel so bad for him, at i certain point i felt like he is not going to make it. I do have a heat lamp on at all time. But was wondering if i put them with the bigger gals maybe i one of them would be their mom? I dunno

Not normally.
I've had cockerels of about a month or two of age, mother chicks. But an older hen usually won't adopt them unless she has been broody.
