Legend---I have a 5 gallon food grade bucket I just sat the turkeys in for brining. Unfortunately, they are not quite fitting in the bucket (2 of them - 13lbs/each), one is sticking out a little. The one might be more pliable and fit in the bucket once it is fully thawed, so I will come downstairs tonight and push them down a bit and yell at them if necessary to get them under the brine completely.
A cover is a good idea if you are brining outdoors. We don't have problems with squirrels or chipmunks in the house, so we are sans cover here.
Turkey tomorrow! Saturday too!
