It most certainly is...like getting a sip of water out of a fire hose..haha!its going to be one heck of a learning curve
...and you'll be under pressure to build the coop cause those tiny chickies will get big fast and you'll want them out of the house.
So since your dad encouraged you to get more than 6, will he help you build a coop?
I'd guess so, as I also guess you're a minor still living with your your folks?
Build a large shed(10x10) with good 12" roof overhangs and open soffits.
Much easier to find decent shed plans online than decent coop plans(most are jut as badly designed as the prefab coops).
