I did learn something about nest boxes and perches in here...I had mine about a foot away, but mine were even with the nest boxes coming off at an angle...well my chickens were roosting in the nest boxes because the perches were even with them...
I had to come in here and learn how to break them of it, and now they lay in them...they didnt at first. I was told to make the perches higher than the nest boxes...hope this helps.
