I bought a trio of Anconas this spring and I've hatched some out. When they are laying they lay very well; I'm getting 6-7 eggs a week from each duck. I
feed them a 20% unmedicated chick starter that I ferment. They don't really fly much at all and they forage quite well. Earlier this year one of the ducks wanted to go broody but I didn't let her as I wasn't set-up for it. I did have a period when they went off lay for a few weeks. It was a very discombobulating time for them as I had to break them from brooding, one was injured by a raccoon and then I had to integrate them into one flock with the Pekin and Ancona ducklings I hatched. It's all good with them now, though.
The Pekins seem to grow about twice as fast and are a little noisier. They don't forage as well, but they're not too bad. It could be that the Anconas,
chickens and turkeys have taught them to forage more. I know my cornish cross have learned to forage from the layers.
I agree with Nicole that they're nice ducks but not really what I'd consider best for anything. I think they're going to be good dual-purpose ducks but they'll have the same trade-offs as dual-purpose
chickens. You won't get as many eggs or as big a carcass. I haven't done a taste comparison yet between the Pekins and Anconas, but hopefully I can in a few weeks. My Pekins
should start laying soon so it'll be interesting to compare the two. Unlike Nicole, though, my drake is a horny bugger who chases the young ducks and drives off the drakes. Good hatching rates, though.
I don't think that they are worth jumping through hoops for if you can't get them easily/inexpensively right now, at least not for me. Next year I'd like to get one or two layer breeds like the Khaki Cambell, Metzler 300, Runner or Welsh Harlequin. The Welsh Harlequin is supposed to be a good brooder too, so that would
be nice. I'd like to start raising the Pekins for meat to sell and I think it's better to have a meat and a layer breed if you've got the space.
Do you have any breeds easily available to you?
edit: I just wanted to add that many people seem to value the fact that Anconas (and any other dual-purpose breed of any livestock) do not put on as much fat as Pekins (or other meat breed). Personally, that's a negative for me as I want to be able to harvest as much fat as possible.
