I also bought the Columbus aqua 5 pack of horizontal nipples off amazon - one on a 1.5 gal bucket in coop near their 5 gal diy feeder (bucket with a 3" pvc elbow, instructions elsewhere on byc) and 2 on a 5 gal bucket hanging under the coop for outside. No leaks anywhere after almost 2 months and hoping they don't freeze in winter as advertised. Undecided if will leave the little bucket in coop long term. Will toss a bird bath heater in the 5 gal bucket in the winter and pray.
"Leaking nipples..." there is a 5 month old human in my house at the moment - agree with above, the title gives me the giggles
