Poorly chicken

[BookMum]

I have an old classic purple eglu for my chickens and have bought a new Go Up as I need a more accessible run.
 

My old classic is still going strong and I want to use it to house a rabbit

Will the rabbit conversion kit fit my eglu which is quite old?

I think it depends on if you have the mark 1 or mark 2 Classic. If you post a photo, someone on here will be able to tell which one you have.
