I don't think there's anything inherently wrong with the happyhutch, it's just that I think the ryedale is much more sturdy, thicker wood, better quality roofing felt, better made etc and will therefore last longer I reckon I'd get through at least 2 Happyhutches in the same time it'd take my buns to destroy a ryedale
Nothing is wrong with them, they are great for the price Mine has had to have things repaired on it after about a year though and it just seems very flimsy to me when I look at it next to my ryedale hutch
The ryedale ones are just stronger and very well made which is why they cost more, and why they will last longer x
