I have had a problem with loss of egg production and honestly tried to put it off as molting and then the heat etc... It has been almost three months of this. For several days I have tried going in at random times because I was pretty sure the hens were eating them and sure enough several times I have found the remnants. But........now I don't think it's the hens doing it. This morning I swear I saw a mouse scurry out of one of the boxes. Can they eat eggs? Mind you we are talking little field mice not rats. The mice we have here are maybe 2 inches long at most. Not very big at all.
