5-gallon bucket with horizontal nipples. The six we have in the coops stay thawed all winter as they're heated to 40F.
For the outside growout pens, those won't fit in the mini coop/hutch so we bought four of the 3-gallon heated ones.
By four days old, chicks are using the verticle nipple bottles and by four weeks convert to horizontal ones in the brooder so they'd already know what to do in the coop. Back when nobody knew, it took one to do it and 8 years later it's just history!
