I called our local farm store to see if the Porcelain D'uccle chicks were coming in and (LOL) and the person that answered the phone that works there said "Oh, I've never heard of that breed" and she had to look it up in Storey's Guide to Poultry Breeds to know what I was talking about. LOL
Put one or two eggs in a bucket and put 1 to 2 in. of water and place her in the bucket for an hour (with your supervision). This will train her that she can't sit down on the eggs. I don't know if it works I just read it in a book.
