what???????

This duck had a deformed bill, but he is still doing fine. I'm wondering if this sack by his neck is normal or also a deformity, I think I saw another duck that had one but not like this.

Here is Pip. She is 2 yrs old. Her comb was a little purple for ages, then it has suddenly gotten more purple. What do you think is wrong/weird? Has she got bad circulation? Any ideas on what it is?
