We ordered the Windsor XXL with and extension with standard shipping. We're using it for rabbits, not chickens. The delivery was super quick, so quick that the recipient went out thinking there were at least 3 days and missed the original slot. Redelivery was arranged on the same day. So pretty excellent considering the £40 difference between standard and overnight delivery. Product itself is OK. Certain parts of the wood on the run had started to split and been glued back together by the seller. The glue was melting due to the extreme heat whilst we were assembling the run so, unexpected mess. The measurements are not bang-on so the coop and run don't fit flush, neither does the roof for the run. It isn't a huge deal, as everything does fit, it's just not flush. The marks for the screws are also not bang-on but common sense fixes that. The instructions are awful. Again, common sense should prevail. It took one person 3 hours to assemble the original and extension with the odd bit of help for the heavy bits. I'd recommend two people. I was a bit disappointed that the extension only extended the length and not the width of the run. As it is, it's very skinny and we intend to DIY a width extension. Can't speak to the fox-resistance of the run and hutch as we thankfully haven't had any predators sniffing about yet.
