Ok ,i have a new to (me) question with the mild winter we had here in west Kentucky my bunnies faired real well now that summer is comming, today the temp. was up near 80 degrees, so now keeping the little bunn's cool and watered is going to be the next thing to get done cool got we live rite in the middle of a woods with lots of shade now comes the questions (watering systems) i want to put in a free flow system with metal nipples on pvc pipe with a small tub and float valve from the well . is this the best ? or is there a better idea out there ??? i dont mind the cost just want something that works.
