If her crop is still full on a morning she may have impacted crop.  She will not be able to feed properly due to this and needs treatment straight a way.  Have a look at the information on treatment on this LINK 

Good luck and I hope she gets better.

Hi Jeanette, I have merged your 2 posts to save any confusion.

It sounds like she has a really bad infestation if you can see them that easily.  They will affect your birds health so here is a LINK  with information which should help.

Let us know how she is and remember you will have to treat all of your birds, coops, bedding.
