Putting my hens on wheels meant I also had to convert my Go to being an Up, and I also decided to get the run extension for the full benefit. All of this was a major investment. Putting my Eglu Go Up on wheels has made moving my hens much easier once I worked out how to use it all, and has saved straining my back. Even with the run extension it is easily manageable. My one criticism is that the foot pedals would be more useable if they were a few centimetres longer as my feet slip off the end too easily due to the short length. As it is I often have to use my hands rather than my feet when I unhook the pedals (be careful not to trap your fingers!). Also the plastic end caps do slip off gradually which can damage them, be sure to check and push them back on or else they will wear out (are replacements available from Omlet?). Nevertheless I am glad I invested in the wheels. As for using the ladder, the hens worked it out within a day (clever girls).
Took one star away because we had two bantam chicks (old enough to be outside) escape through the gaps where the wheel lever is. We had to close it up with wire until they got bigger.
I am very pleased with the wheel set
Just upgraded my Go to a Go Up. Decided to add the wheels just in case I need to move the run on my own. Unlikely to need to do this very often, just gives me the additional flexibility. Quite expensive though for what they are.
