All in all they get along, I got rid of a few scared (at humans) and aggressive ones and it made the whole flock nice and calm. I have only had one duck go broody and when she did EVERYONE ran from her. even the most aggressive drakes ran! =)
off topic question. i read on a chicken thread that they are nice when they are laying and once they go broody they stop laying and that is when they get mean. is this true with ducks too?
her eye is perfectly fine , just a different color than the other.
Ducks don't lay once they have finished building their clutch to sit on, and yes trying to get a broody mama to cooperate is rough, I have a few that will latch on my skin and not let go, most though aren't too bad. But when they come out for R&R daily you can bet any one in their vicinity is going to get as far away as possible she is all grumpy and will go after anyone close by.
