As noted, a wet mash of their feed is great bc it doesn’t dilute their nutrition.
Eggs -hard boiled, scrambled are fine too. But can sprinkle this on top of wet feed.
Chickens are prey animals. In their minds, hard wired, they think EVERYTHING will kill them. And they are likely to stay “unfriendly” or skittish until they begin to lay. Once they begin to lay, usually they get more friendly. Some chicks are less skittish, of course. Some are more skittish their whole lives.
You can make sure you are out and around them, they will get used to you. Keep in mind though that new things can freak them out. A skirt, different colored pants, swinging laces on shoes or boots all serve to freak them out. And plastic bags - they will hightail it to get as far away from you as possible, for some reason chickens HATE the sound of plastic bags, although I’ll guess they could get used to the sound eventually. But a plastic bag in the wind WILL kill them in their mind.
Being around them, sitting down for them to get used to you, being consistent, are all ways for them to have the best chance for them to be friendlier to you…but it might take until they lay for them to be really friendly.
Good luck.
