A new plant in their diet is a really good suggestion. This is the time of year when new things sprout, and every year is a little different because of weather patterns. I have some years when selenium reaches toxic levels in my pasture, and some years the locoweed, or the gumweed, or the pigweed is really prevalent while other years we see hardly any. It's definitely something to look into. Your local extension agency may be able to help identify possible toxic plants, and if a certain plant is unusually prevalent this year they'll have probably heard about it from local farmers.
