That is not where I would want lights. It will fool birds into thinking day lasting longer than it does. I suggest for short term placing a night light like used for small children and placing it in the coop. Have it running 24/7 for a few days. At same time have the lights under eaves turned off until some time after dark. If goes as I expect, then as daylight deminishes the birds will gravitate to lighted coop area through / over ramp without being destracted by exterior lights. Once birds get used to going into coop on their own you should be able to turn the eave lights on as doing now..
