We have a male & female Magpie & a female Blue Swedish. Then, we have 2 male & 4 female calls. They have all been brought up together and everything seemed fine until lately. The male Magpie has started mating with his "big girls" - no problem. Suddenly, he decided he likes one of the little call females who doesn't seem to care for this big lug chasing her around. He has caught her a couple times and seems to be trying to mate her, but we always intervene. We aren't sure if a duck that is so much larger could actually manage to mate with a little call, but we are concerned he could hurt her. Does anyone have experience with this? We would prefer not to keep them separated all the time. She can fly and he can't, but she doesn't fly away, which she could easily do. They free range in a large area, so boredom isn't the problem. Thanks for any info/ suggestions.
