I made one last night, had to use caulk on the inside because I am not a carpenter and wanted to make sure no feed got stuck where it could rot. I am concerned about the caulk in contact with the feed- should I use paint or a sealer?? I found the following link with some suggestions, looking for more. http://hartkeisonline.com/2013/08/23/choose-farm-animal-friendly-paints-says-paint-expert/
No. If you used a silicone caulk you should be alright. In my experience most paints will come off the caulk especially where it is flexed a lot, like chickens pecking the food off of it. The chickens will with a little time wear the paint off the wood as well. If it is going to be used it where it is fairly dry I would not have bothered with the caulk. Just a dump and a thump to get the old feed out of the cracks every once and a while.
