I finished my outside pen for my 1 male and 2 female blues, they are a little over two years old. The pen is 12x26, 10 feet high. Every thing was great, the male was breeding and everone was getting along. Now all of a sudden one of the females will not stop harassing the other one. She won't leave her alone! She chases her all over, won't let her up on the perch, this goes on till their both exhausted. It seem to start when they started to lay eggs. Would this have something to do with it? They just lay their eggs on the ground. Should I build a little nesting spot for them? They used to be one big happy family, what happen?
