Oooh, welsh harlequins for sure! I currently have a welshie drake, and he's such a sweetheart. I got him when he was already three weeks old, but he would still climb into my lap and let me pet him. Now that he's grown, he's still the sweetest duck I have - even sweeter than the pekin duck that I raised from less than a week old. He'll come over and sit next to me whenever I'm in the yard, and he brings my mallard drake and the girls with him, so even though they're more skittish, I still get to interact with them. And, he's such a gentleman with the ladies. I've never seen him be rough. Really a great bird. Plus, welsh harlequins are known for their calm disposition - metzer says that theirs are even calmer than their pekins, and I'd have to agree. Females also lay just as well as khaki campbells, because the breed was actually developed from off-colored khaki campbells, but they have better mothering instincts and are less nervous. Also they can be much prettier. That's my opinion, but I might be just a tad biased

I have some hatching eggs on the way so I can get a few more myself!
