Looking for a mk2 cube and walk in run/ attached run in good condition.

a Walk In Run in Camberley that has recently been listed on Facebook Marketplace.  It is 4m long x 3m wide (x 2m hight of course).  No Cube for sale, just the run.  Nothing to do with me, just saw it today.

Hi, we have a full height 3x3m run available. Had a baby and cannot give the chicks the time they need. It’s in good condition.
