tell your daughter good work and good luck at the fair with her pig. And a learning curve it surely is---I put out a block for my sheep yesterday and they attacked it. I took it away for a day and will probably put it back tomorrow. It said not to give them too much of it to start out.
My cows did for about 3 days and have backed off of it now. My fly trap is working great. Probably 30 flys and only been up for a couple hours. Also the cows haven't really been around it yet.
