Hi, First of all try and relax!
I have been out all day and just saw the thread. Here is what I would do with one of my birds. There is a lot of good advice in this thread but you can't do all of them at once. First of all as others noted I would not try to empty the crop yourself unless you have been shown by an avian vet or experienced bird person, just to risky. If the crop is partially full you can mix some warm water with ACV (Tsp/pint), with a few drops of red palm oil, or a pinch of digestive enzymes. If you massage the crop it has to be done gently and slowly, yes you can aspirate your bird if you are not careful . The next feeding I would add 6-10 drops of ACV or a pinch of digestive enzymes to the hand feeding formula. We keep Harrison's digestive enzymes here, a pinch of a quality product from a health food store would not hurt. Keep in mind some hand feeding formulas turn to cement if they are not mixed with enough water, should be stirred and stirred. Here we mix formula in a small blender. You can also add a pinch of probiotics to the feeding formula, Avitech makes a good product.
Again there is lots of good advice in this thread, digest what everyone is saying, ask questions and above all, use common sense.
I feel feeding formula 50-60cc 2X is plenty as the bird should be eating some on his own.

We are all here to support you through this.
I would say she is acting much better than earlier today, though still every few minutes making a light scream, not exactly begging to be fed like usual, but I think that's what she wants. I will call and get her in as soon as possible in the a.m.
Glad to be home and know she seems to be a bit better. I will decide tomorrow if the crop is completely empty, if I should just go with the additions to her formula, or take her in to see the CAV anyway just to be safe. Susanne Holly is now on two feedings, it was the morning one I had just cut out in the last few days. A friend who raises RFM's told me to start to back off every two days on the amount of the night feeding. And had suggested I cut out the a.m.. It just seems to send her into this terrible place that she won't snap out of. She gets worse as time goes on{I tried this before} she starts to become angry, and tries to bite..normally she is pretty sweet, so this is not normal. I don't want her to see me as the one who starved her...she might begin to hate me.
prayers and thoughts plus lots of positive energy coming your way!
