I got four welsummers at auction about a month ago, and they've been leisurely molting ever since. Pinfeathers are coming in, so no worries there. I think they started molting and that's why they went to auction in the first place. But I've scoured the web, and have found NOTHING about whether welsummers are "late molters" or "early molters" or whatever, and was hoping that someone with welsummers could weight in what their experience has been, and how long it lasted.
