The chicks' first full day in the coop went great. It was a true testament to their tolerance for noise - the neighbor on the other side of the coop had his house power-washed just a few feet away from the coop, and it took most of the morning. In addition to that, I had my power tools out there cutting wood and hammering things working on the chicken run a couple feet from the coop as well. The noise was at the "cannot hear conversation" level. But the chicks were totally fine! Kicking around the shavings, chasing each other and going about their business. At one point they piled up by the door (closest to where I was working just outside) and groomed themselves, then took a nap in a fluffy pile of shavings, as the noise was still going on full blast outside. Those chicks are VERY noise hardy!
In the afternoon, the kids and I talked to them through the camera's speaker. Didn't freak them out at all. They perked up, then ran over to the camera and stood under it, looking up, looking for us 
 
We went out to pay them a few visits throughout the day. They were happy to see us. Both kids love the chicks and are excited, but my 4-year-old son is a lot more interested in them than my 6-year-old daughter. He's more of an animal person, and very patient and careful for his age. He and I sat there for quite a while just watching the chicks, and he carefully picked them up one by one and held them in his lap, petting and hugging and kissing them 

 At some point I should probably put a ban on the kissing part... But he was so sweet with them. Most of them let him pick them up and hold them just fine, and didn't run away when he let go, but stayed in his lap for a while. We are really enjoying these chicks SO much!!!
