I understand what it's like with chipmunks for the first time, you can just loose so much time watching them, I still do. They do get up early, first one of mine to get is Toto, she starts at 6am normally. As I write she's gone to bed now tired right out, but still got three running around me.
Don't think it will be long before they start to jump on whoever is in their home with them. I suspect the women you got them from go them hand tame, so in no time at all you will be frisked by them when you go in.
I didn't press it, but so glad you got it double meshed. I'm not a cat hater, but cats are very efficient at what they do, and chipmunks are especially appealing to cats, probably because of the darting movements and swishing tail.
Food wise, they will have their favorites, mine have sweetcorn everyday, and a quarter of pomegranate in each aviary when I can get it.
Mine tend to have a drink when they get up first, then throughout the day. When thirsty they will spend about 15 seconds sucking water out of the bottles. If they have just had a particularly vigorous chase they will go for a drink. Have more than one water bottle, this is in case you go away and one bottle runs dry or leaks, then they always can get to water. Although I also provide mine with water bowls, try to avoid them. As water bowls need changing a lot (about twice a day), as chipmunks can drink even when they have their cheek pouches full of seeds, so the water will end up with seeds and other food floating in it. With the water bottles I fix them so the spout is about 8cm above the floor or shelf. Thinking about it, I probably only see mine drink because I'm with them most of the day and I have more chipmunks. So even in a day I won't see each one getting a drink, so I'm sure yours are drinking OK.
Trying to get a photo is like trying to catch them, near impossible. If it wasn't for the invention of digital photography I wouldn't have any photos on this site, perhaps just one or two of a tail going out of shot. Can't imagine how I would get a decent photo if I used a roll of film, just 36 chances, no chance
