Hello all. I am new to this whole process so there has been lots of trial and error. I have also had some bad advice from other sources and made some errors because of it. I have a lot to learn and would appreciate your input!!! My chicks are now 17 week old Buff Orpingtons, ten of them, and 14 week old Black Austerlorp, 13 hen and 3 roos. Here are some pic's of my coop and runs. The following are pic's of the connector tunnels I made. There are drop-in doors which make the coop secure at night. The chicken wire at each end of the tunnel allows me to move the runs around the yard to some degree.
