Welcome to the coop! I use the Forums and Articles tabs at the top of the page to do research. You can get lost for hours. It's nice to know you are minutes away from getting help with questions and emergencies!
Get a Costco shed and add the particulars. This way you can walk inside them. I could have two sheds with the price I have invested in what OI have now. I still can't walk in them.
Hello and welcome to BYC! Glad you joined.
There is a lot more to designing and placing a coop and run than most newbies realize. I suggest you spend several hours reading threads in the Coop and Run forum and read the higher rated Coop Articles. Good luck.
