yeah, I say mareks just because often a bird exposed to mareks will succumb to something else because their immune system is overwhelmed with the mareks. And watching her this morning, well she has the muscular issues mareks has - and she won't swallow. Poor baby. I know I could force feed her by tubing even with food her prognosis is so poor I hate to put her (and me) thru that. Although her crop was empty yesterday, she had two totally normal droppings overnight but again, no luck with food this morning. She just let it fall out of her beak, ditto with liquid.
So sorry for you and your girl.
