Gave the chicks back to the hen, but I still brood them in a brooder at night when I am asleep, but she has them all other times. The hen seems to see me as a co-op brooder which helps, she is completely fine with me taking and holding the chicks and is just as happy to take them back.

When with the eggs she'd attack my hands, but I can put my hands under her to get the chicks with 0 issues and the chicks often come out to see me anyways.
She and the chicks went outside for a little today, the chicks sticking with the hen but occasionally wandering to me also. She did her food chuckles and called them to food, and the clumsy things sprint in and face-plant on the offering.

Though the hen went back inside to her nest, which I made 'steps' using weights for the chicks to be able to get into easier, and they followed. I then put a fan by the nest so the hen can keep cool as it is a very hot day today and she was panting, the moment the fan was on, she poked her head out of the nestbox, rested it on the lip, and just closed her eyes in complete relaxation.
Had a little scare though when they were out, went inside to get and drink and came back seeing just 4 chicks around the hen instead of 5, the 5th was in a tuft of grass just tall enough to hide it, pecking at small insects not too far away from the hen and other chicks.
Also, my cat learned to stay far away from the hen when she has chicks. Angel got too close for the hen's liking so the hen chased Angel and pounced her, I saved the cat from the hen and neither had any injuries, barring a small tuft of fur the hen had pulled out.
The chicks were super confused and first ran to me and then followed me as I went to save my cat, and the rooster was doing his "what the hell is going on!?" scream that sounds like an old man yelling, and the older chicks just... Stared and then continued to forage.
