I hadn't considered that. To be honest I didn't know that I'd have to feed dry over the winter although "winter" down here in south Texas really isn't cold.
Thanks for the help!

I know that a lot of the people who feed FF just keep feeding it through the winter. I decided to feed dry because it gets so cold here. January through February the daily high is usully around 20 below. I just didn't want to be thawing out blocks of FF a few times a day.
