Oh Tari, your doing fine a Que is normal. :-)
I believe it's just that we watch our Greys like a hawk and grab a camera and shoot photos or post a description of what they did. Your a quite a bit more busy with your other birds and tasks. We probably do spend more time with out Greys a little more than you, but that's because we have it.
Dayo does not play all day long and go crazy. He, for the most part is happy to sit and watch whats going on, preen, eat, vocalize at times etc. But it's not like it is constant.
We do spend "snuggle" time with him every evening from 630 to 8 and he just loves snuggling, getting scratches etc. and then off to bed for him.
Every household is different and so is every Grey, so don't be hard on yourself!! :-)
We all know you love all your birds dearly and spend as much time as you can with them.
