We have a small herd of 12 ducks - one is a Blue Swedish Drake, then we have a female Blue Swedish, 2 Golden Hybrid 300, 3 runners, 4 white crested, and a Cayuga. The Cayuga is almost a year old, but the others are about 6 months. Our drake is fairly large compared to the others and very exuberant about mating, so most of our cresteds have bald heads. But this morning, i was getting ready to post asking for help with our blue runner whose legs seemed paralyzed and jutting out behind her. But as i was searching to see if anyone else posted a similar problem, she stood up. She's in our office now in a laundry bin. She actually looks like she is trying to lay an egg. When i found her earlier, unable to move her legs, she had been in our little pond (kiddie pool) and Mr. Lucky had just finished mating her. She tried to get out of the pond and couldn't. So my question is, could his mating cause internal damage? It's clear the damage he causes to the heads of the poor crested girls. i'm wondering if we need a drake at all. We don't want any more ducks, and i'm thinking the girls might be happier without a large male chasing them down and jumping on them several times a day. Would appreciate any advice or input from other duck owners.
