Is this a lone chick or are there other chicks being raised with it? Often dampening feed is a way to entice a reluctant bird to eat- such as birds who have been injured, birds who are stressed, etc. The reason I mention this is that if your chick is a lone chick she is likely stressed by that situation and a reluctance to eat/poor appetite may be the result of that stress.
If not a lone chick - are the other chicks in the group eating dry crumble?
As pointed out, wetted feed is difficult to keep - so it must be fed in controlled feedings vs. left as a "eat at will" sort of free feeding approach. There may come a time where this is no longer something you wish to have to do.
If you wish to transition your best bet is to approach it as a gradual thing. Example - prepare a bit or wetted ration and place it in a dish, then sprinkle some dry crumble just as you present it to her. If the wetted is not sopping wet, the dry bits will remain dry (or mostly so). Simply increase the amount of dry and decrease the amount of wet progressively and the bird will be eating all dry at the end. You can also present dry crumble on top of any/all treats you offer so that the association is positive between dry crumble and really desirable food.
