I understand you want to build your own coop. I do think you need to take a step back. If someone wanted to bake a wedding cake but has never boiled water much less an egg. I think it would be clear a wedding should not be their first task. I think if you start with the idea that down the road you want to build your own, but for now you want to learn the tools etc. I assume you want a coop now... in that case find a friend, neighbor, who can build a coop with the condition you want to help and learn and not just watch. My father was an excellent carpenter. I grew up thinking that guys should just know things about tools. In my 50s I started wanting to do woodworking. I found out that many men were like me and knew nothing about power tools etc and when they retire they start from scratch learning wise. Young or old dont be shy to find that person to build your coop and let them know you know zero and part of the deal is they let you learn. Good luck!
