select all inputs except hidden (but with one exception)

select all inputs except hidden (but with one exception)

Lets say I have a set of inputs on a form:
<form id="myform">
<input type="checkbox" id="goat_1">
<input type="checkbox" id="goat_2">
<input type="text" id="pig_3">
<input type="hidden" id="cow_1">
<input type="hidden" id="chick_3">
<input type="hidden" id="duck_5">
</form>
I want to select all inputs, except type="hidden", but with one exception
I DO want any hidden input with an id beginning with "duck". I need this
all in one array so I can iterate through it.
So the first two parts are easy:
$("#myform").find(":input").not("[type=hidden]").each(
function () { alert("do stuff"); })
But what about the exception?
I am looking for the cleanest way to do this (prefer one line/statement).
