An acking bird on the first day, as strange as it may sound, is a pretty good sign. Most really scared keets will sit quietly, hiding in a corner, for the first few days. It's a good idea to have both food and water where they absolutely cannot miss it (keeping some on the bottom of the cage and the top is good). They'll catch on eventually.
My new keet has taken a few accidental baths herself, hah. It's kinda funny. I came home from work today and she was soaked, and I know it was due to her clumsiness.
How big is your cage? If you can cover the whole thing with a T-shirt, it might be too small for two. They need space to feel comfy. Of course, they will be ok in it for a while, but consider that for the future.
Other than that, it sounds like you're doing fine. Just give them time to get used to you and their new home, change their food and water daily, and when they stop running from the scary-giant hand, it's time to start finger training. Sounds like you've read up on all that...so good luck and I hope everything works out for ya
