Mel - beautiful log!!!
That idea is quite intriguing! Now you've got me pondering again hmmmm
How cold could it get and still stay open? I know they circulate ponds and horse troughs but, of course
the water in those is much deeper than it would be in a water trough for a chicken... hmmmm
Have you done this before or seen it done? Photos or website of how to set something like this up?
Mine do that from time to time too. Eat them, then won't touch them.
I always wonder if it's possibly because something changes ... maybe the worms are carrying something that the chickens can tell they shouldn't eat? Maybe at certain times in the worms cycle it puts off some kind of hormone that isn't tasty? I really have no idea but I know I observe that too.....
