It's only going to get warmer as you use it and work with it, until and unless you can get it back into a refer. I usually do 4-8 birds at a time when brining, in 5 or 6 gal buckets. I use plenty of ice while mixing my brines. I store the buckets in the garage when its cold out. It is usually between Thanksgiving and Christmas when I do turkeys. If its not very cold out, I put gal. size ziplocks full of ice into the body cavities, and in the buckets to keep the brine chilled without diluting my brine. Poultry is pretty touchy about proper storage and cooking temps and bacterial growth, particularly salmonella, but others as well.
