Tips for new broody chicken mama?

Made another post a little bit ago in a frenzy as I realized our broody hen is FINALLY hatching her babies! I have incubated chicks from birth before and raised them inside but our hen started brooding on some fertilized babies and I’ve decided to let her- saves us a lot of stress and mess if she can be a good mom!

But I do really want these first ones to make it- at least one or two so I can see how well she raises them. So, as an overthinking worry wort, any advice on how I do this? 🤣

Things I’ve already done/have worries about-

Other chickens had laid a bunch of extra eggs under her so during her water and food break today I managed to move the non-chick-eggs from the originals- she’s an Americana or Easter Egger, so doesn’t have as much floof- now she safely fits over her original six I think

Water/food- I have a baby water’er and a big waterer, I brought the big one in and have the baby one in there as well- I know drowning is a possible issue, is it as much of an issue with a hen raising them? And I have non-medicated chick feed in the food bowls and am going to get some oysters for the big hens but they don’t really eat them 💀

Our main feeder is a bit tall too, I do have a baby feeder but naturally I worry about if they’ll find the food and the water or not-

Lastly- their the nesting boxes are on the wall on shelves, the coop is full of soft shavings and it does have a ramp up and down but I still worry about how our girl will lead them down to get food and water and things.

And lastly as per my previous post- so worried about them getting shrink wrapped 💀 have had bad cases in the bast where chicks couldn’t make it because of issues from this so- yeah.

ANY tips advice or suggestions you have please let me know!! Might not comment on all and probably know a good bit already but I want to cover ALL MY BASES because I’m seeing a lot of the same answers over and over and don’t want to realize that I was asking the wrong questions too late you know?

Like- when I was doing research for ducks and chickens mingling or not everything was just advice on how to introduce them properly till I asked Reddit and found out about the actual risks in mingling- don’t want that to happen-
