Need Help to Finish Coop

[CalvinBrownie]

My 4 chickens are about 3 weeks old now and I think I’m done finishing up the coop and run all I need to do major is build the netting structure on top of the run. But what else do I need this is my bare bones set up I’m gonna make it look nicer in the future but now it just needs to work and keep the chickens safe. What I’m thinking about doing it’s putting chicken wire on top of the coop under the tarp and in the future adding some troughs to put oyster shells and grit. The log in the coop will have a 3 gallon waterer because it’s really hot where I live and the nesting box is a old rat cage that I manipulated to look like that I could also use a 27 gallon Costco tote but my biggest concern is I’m taking up too much space in their coop area and if the dust bath is big enough it’s just a Costco 27 gallon tote. I also saw this YouTube video of this guy using a dog kennel for a coop, I thought it was genius because where I live it gets to 100 during the summer almost everyday so they have a lot of air coming in. It never snows in my area and rarely goes down to 30 degrees in winter nights
