Broody hatching eggs!!

[Harestad Farm]

So we are new to the "hatch your own " thing.... We have 2 broody hens sharing one nest (it's pretty cute) one egg just hatched. And I'm assuming we will get at least a few more out of the 13 eggs.....
My question. Because my nest boxes are raised, and because I have 2 broody hens sharing one tiny nest box, there is no room to put food or water up there... I added a platform in front of the boxes but I'm not sure the baby chicks can hop out. So how long before chicks need to have full access to food and water? Right away? Should I kick one of the hens out to make room for the food/water? Should I move one hen and the hatched chicks out and let one hen play momma in an area with food and water and let the other one play Hatcher? Or should I just move the whole crew (momma's, eggs and chicks) to a spot with more room?
And advice would be appreciated

My broody just had a hatch last week (4 out of 7 eggs). She was in a milk crate nest elevated about 3 feet off the ground. I left her to sit there for the 3 weeks, but it wasn't ideal for the babies because they could have easily fallen out. I moved her to the floor with space for a small feeder as soon as I heard chirping. My hubby fashioned a little cardboard ramp for them to get in and out easier. It has worked out really well. This was our first time with a broody (and hers too) and I was amazed how feisty the chicks were right out of the shell.

I'd definitely separate each Hen with eggs into separate Brooder set ups and not have two Momma Hens on one nest.

I'd move them both to side-by-side nests on the floor. If they like being together, why bother them. I had two broodies in different nests hatch at the same time. As soon as one set of chicks saw the other chicks they were all best friends and moved in together with one mama on the floor. The other hen camped out in the nest directly above. They both raised the chicks together, with the hen on the floor being dominant. As the chicks got older, one, then two chicks moved in with the broody above. The hen on the floor was like, "What the ...?!", decided her job was done and went back to the roost. Then the other hen raised them all until weaning. It was pretty dear.
