That sounds fabulous. I'd absolutely love that. Allowing kids to express themselves and show what they know is just the best thing ever.
If you want to keep it going, you should ask advice for what to feed them, what they need to drink, how often they lay eggs and do you have to put them to 'bed'.
I'm sure you know all the answers already, but it would be lovely to encourage her.
You may want to think about a few things that you know, that she may not, and start sentences with "Did you know that...?" so that you can help expand her knowledge. It'll also endear you to her forever :)
