I have been doing searches on the internet and have not come across a clear answer, so I'm posting here. I'm sure you'll be able to help me out! I got my first ducklings last month. 3 Anconas from a local breeder selling at a flock swap. Boy do they grow fast!!! They are HUGE! And super duper cute! LOL. Anyway, I have the 3. I is much much bigger than the other 2, and they are the same age. Does that mean it's a boy and the other 2 are girls? I have never had ducks before. Do ducks need to be in pairs instead of flocks like chickens to get them to breed? Thanks for your help! Oh, he also said he had blacks and lavenders. I think I got all blacks, though. That meant the spots, I assume, right? One was solid yellow and he said it might be a lavender, but I think its spots are coming in dark, not light gray like what you'd call lavender on a chicken. I also picked up 4 Pekins at the feed store last week and they are adorable. 2 have little knots on the back of their heads and 2 don't. Does that mean anything as far as sex? I also have some runner ducks coming with my hatchery chick order. We are excited about getting ducks, but I obviously have a lot to learn!
