I'm still sorry to hear you want to give them up. Maybe you can make toys for them at home. Beads on a strong/safe string work well. As for the vet thing, I can't say that's enough of a reason to give them away. Is there any way you can convince your parents? Birds get used to you, and its hard on them to be rehomed. Please reconsider. I don't know how anyone can give their beloved pets away unless they really really have to.
