Some people ask a lot of those around them

She doesn't sound like a very good friend with her requests

Offer the hens for her car.

Yeah. Also, you have to feed chicks for months until they get to a point in which they can produce. There’s a lot of work that goes into an egg laying chicken. And it’s super crappy to get upset that someone didn’t want to just give you a third of their flock.

she can afford a few acres of land, she can buy chickens

Sounds like she wants the farm life with none of the hard work.

depends on the situation but could lend her 2 or 3 hens till she raises her own but she sounds like an entitled twit I'd tell he piss off.

If they're cheap she can get them herself.
That said, as long as its not a big deal, I don't see the problem in lending a friend a hand.
I don't think either choice is wrong.
