I worked a side-job and saved up for 6 months. I had a foundation poured and a coup delivered. It looks great and it is done right. It is not an eye sore. For me personally, it was worth paying to have somebody else do it for me.
I'm new to raising chickens so I'm no expert, but I read to give them access to chicken food all day and then take it away (or put it in a safe container) at night so it doesn't attract rats. Then put the food out again in the morning.
