I'm in Tn. and I only had a kiddie pool last year for my 2 pekins. The water would freeze solid sometimes and I would have to wait until it thawed enough to dump it. I had those rubber pans from TSC for their drinking water and it was eaiser to dump every day and give them fresh water. This year I added 13 runners, 3 welsh harlequins, 2 black and 1 blue swedish and 4 geese. I added a larger kiddie pool and several more pans and some 5 gallon buckets. I hope that will carry them thru. the winter.
