My hens are free range and my coop is from a converted pickup shell. A scrub jay mating pair that has a nest in the yard. I hear the chicks in the nest in the tree. The nesting pair of Scrub Jays get into the coop, and destroy most of the eggs most days. I have tried curtains in the door of the coop. This worked for a few days. Then I hung fine birds netting over 14 feet around the coop. That worked for a few days. The scrub jays seems to figure out how to get into the coop. I want to keep the hens free range and the scrub jays out. I think that once the chicks leave they Jays will leave the area. How do you keep Scrub Jays out of a free range coop. I know putting mustard in eggs will prevent hens from breaking the eggs, does this work with scrub jays as well?
