If you're opening an entire wall or near to it, one is good. It should be facing away from your prevailing wind.Yes that front wall will be open up top with hardware cloth. Thank you! Also the wall with nest boxes has no venting. Do all walls need it? If so is it bad to place a covered vent with fins close to the floor or should they all be up higher? Thanks for putting up with my questions.
That’s great to hear. Thank you!!
