It would be hard to post pics of this. its just a fenced in "hoop" made out of 2x4 fencing. I have a small chicken door with the hoop fencing connected to it. I have a huge long fence line with a arborvitae hedge in front. it goes in the hedge runs 75 feet or more then the hoop pops out at the end of the yard into a fenced grass area. just picture a upside down U. anchored down to the ground with stakes. it is only for when we are home and around, it is not animal proof at all. it lands in a totally unprotected area with temporary fencing around it. one mistake we made to start with was making the tunnel too small and they were afraid of it. no matter how many treats we had. it was enclosed and very dark behind the hedge. we made it bigger about 2x2 and that fixed the problem. once one chicken made it down it only took a matter of time before all 6 figured it out some were a little slow. we baited them all the way down the tunnel. it was probably a few days before they all caught on. we were so surprised when we opened the little chicken door and went about our business. just to find them all down at the grass area!!! yeah!!! all the work paid off. working behind a arborvitae hedge with a fence behind that is hard work! wear thick clothing...
Good luck!
