They want nothing to do with the nest box i havent seen one go near it. Its 3ft high is it to high? I'm going to add golf balls so they know what to do but if they dont go near it im not sure how it will help. Do i need to lower my nest box some how? i bought it off of eggcartons bc my dad got to lazy and was wondering if the wholes were to small. they are a 12x12 at least thats what the thing says i better measure.
