They DO look like Ancona.... HOWEVER.... From what I have seen, Ancona tend to have white underbelly and more broken up spotting. I honestly think they look like Ancona alot, but may very well be Ancona-Black Swedish cross!!! That would explain the bib of white on the breast, the black belly, and it would also explain the white tips on the end of the immature wings. It would also explain the spotting on the bill and feet. The second pic looks like a crested khaki Campbell.
I love ur birds. Can I have them???? lol. But no, really, can I?
