This is why I prefer having small bantams. The small poops are hardly a burden. During the summer the flies come to eat the fresh poop and leave again when they are finished.
My neighbours cats probably deals with every young rat that comes around. I have no trouble with mice nor rats. * I even leave the leftover feed in the run at night. The chickens don’t mind to have breakfast directly after sunrise (auto pop door with light sensor).
But don’t mention these

to the irresponsible friend.
*Oops, I’m afraid Shadrach is getting jealous now.
