far and above, my ducks favorite water container is this 6.5 gallon rubber tub. they will stand around it bobbing in and out. I would like to use it all winter but it of course freezes. I have heated buckets, but they seem to use them out of necessity not for enjoyment. I would like to put one of the galvanized heaters under it, but I am afraid of it off gassing some kind of toxin, has anyone done this? any experience? I used these bowls, 4 and 8 quart for them all the time for peas food etc, they are great because they can't break, the clean up easily and they are inexpensive, also, I figure it is easier on their bills.
please advise
