Should i worry about my ferrets while i am away for two weeks?

I am away to cornwall for two weeks and i am really going to miss my little weasels. I am giving them to a very good friend of my mum's who knows about them, has had them before and whose boyfriend is absolutely ferret mad! there is also a vet down the lane, and another ferret handler. However, as she has recently come out of an operation from cancer, the chemotherapy has lowered her immune system, therefore she gets colds now and then. It is almost over this one, but we are dropping them off today? ......How can i put it nicely to say, be careful???? Bear one of my eldest males, is an angel, he has never bitten and he is perfect. She really took a shine to him and i am worried that she will handle him too much, and pas on her COLD? I do not know how to say it but i will feel bad if i don't. She will i', sure look after them as she is great with animals, but i am a little worried, as you would be. They will have my old double decker hutch which is now hers, and a single one just in case. Also, she has a conservatory ferret proofed, which is only for ferrets. What should i do with them on my last day for two weeks????? thanks.
