Need tips from experienced chicken owners

I have my 4 chicks in this temporary custom house I made, they got a feeder, water, and a heat lamp.

I change the shavings daily and always make sure they have water and organic feed.

I've hade them for 4 days now.

I'm planing on getting a nice coop for them, found a awesome choice from Amazon, about $109.

I need some tips of advice from some who has experience since this is my first time raising chicks.

Incase you're wondering, all my chicks are females and are sapphire sky chickens
