I had to deal with a guest rat just the other day, he just popped into the coop for a spot of dinner through the delightful tunnel he had created. In spite of Mr Ps efforts to rodent proof, they're cheeky little fuckers.
Can't wait to see that happen on Hunch NotaFarm.
Tbf though, I don't find them time consuming in the slightest. 15 mins a day to feed, water and clean poo out of the nest box and maybe 45 minutes once a week for a deep clean. I know this is Sopha world where even lifting a finger for a minute is hard work but in actual reality they're quite an easy pet, but then I only have two. I imagine the more you have the longer it takes.
