Any ideas for keeping the crows out of my nesting boxes? They ate three eggs yesterday (wished I had picked them up ten minutes earlier when I saw them!), and I caught one trying today. I thought it was a snake, as there was no trace - but apparently I was wrong. Do the owl decoys really work? They are coming in when my gate is open for the girls to free range. Otherwise, the bird netting keeps them out. Thanks in advance for your input.
