Yes they're delicate now, but in three weeks you'll be wondering how soon you can put them outside. It's not that you're tired of them, more that they're really not house pets per se. Mine just went out Sunday afternoon. They really seem much happier on the ground rather than in a box. Almost immediately after I put them out, the temps dropped to the 40's with all sorts of rain. I've been worried about them--I shoot straight out of bed at the crack of dawn to check them--but they seem to be okay. In fact, some of them really seem to be prospering in the "out of doors". The one we used to call Runty we really can't anymore. She's almost caught up in under two days of fresh air. The point is, just have fun. Allow yourself to enjoy them for what they are and what they mean to you. It's just like the people that you love, you can't protect them from everything. Spend a reasonable amount of time protecting them, but spend most of your time enjoying them.
B/C your Ameraucanas are more than likely mixed breeds, their temperament can be all over the board. I have two myself and one is everybody's favorite. She's very personable and was the one that liked to be in a person's lap the most. The other is perhaps the most stand-offish of our dozen chickens. She hates to be picked up and is the first to run from people. That said, I happen to think she's the prettiest bird we have too.
