Building a second rabbit run...

Right so long story short guys... I have a rabbit (Mopsie) at the moment, he was paired with another boy who I lost this time last year 😔 ... I wanted to give him some space before he met another bunny to see how hed cope and initially he was great but now he seems a bit low and Ive got a bunny date arranged for this week with another rescue bunny ☺ ... Ive already got a hutch and run but I was thinking of building a second run so that they could live alongside each other to ensure safe bonding.

Im looking for ideas on materials, levels, hiding places to make sure its the safest place possible for hopefully the new little lady. And then when they are bonded properly I'll just attatch the tunnel between the two so they can both have free roam of both. Mopsie is an outdoor bunny 😁

Thanks in advance guys x
