It's a low chance that I might take them so I guess that I'll just tell her to find someone else.I depends what you think is too risking.
If you only have one place to put them and that is in a crate in the coop it sounds like that may be your only choice.
For me, it is too risky, you can't see everything that they may have and transfer to my flock.
I wish you luck!!
I might tell her to ask on BYC maybe then.
