I know I am enquiring a little late in the day, but as I just joined, How is Peanut. Hope he did ok, if the crop seems to not be emptying fully a little warm water and massage the crop can help; if sour crop is suspected a warm water flush can help providing you catch it very early on in the problems life. then it flushes and feeding can continue normally, ( if I am wrong plz tell me someone, never too late to learn)
