Our babies seemed to do that also- every time I checked on them during the day,, they were napping. But really it would be a 3 minute nap, then up and running. And they had parties going all night long. They would be peeping so loud, like they were distressed, which got me adjusting th heat lamp, and thnking they were hungry, or too cold, or too warm.. No, the reality was they were just crazy. And tried their best to drive me there with them- and they were in another room with the door shut.
So, is it "normal"? LOL.. no But typical, in my eperiences, yes.
I have some 6 day olds in the coop outside right now , it's almost midnight and they are playing loud music, dancing and singing. I think there is a poker game going on, as well as a game of tag. As long as they don't invite the neighbors, or disturb the old hens, I think it'll be fine.
For yours, you might try putting them in a different room- it could be them hearing you that is keeping them awake. If you have a heat lamp on them, a red light is more calming than a white light to them. If you do not have the heat lamp, a little nightlight might help keep them calmer at night ( Mine always seemed to like it better when it wasnt pitch dark)
