My jar of palm oil says to NOT refrigerate on it. I don't know how it could hurt it other than making it more solid.
I've found about the only way joey will eat her palm oil is to put it on a small part of bread and toast it , it draws the palm oil in and she loves toast.
I tried straight from the spoon the first night and that didn't work too well. she'd dip her beak in it and then fling it everywhere!! walls, carpet, curtains, my face.... nothing was safe. At least the toast keeps that from happening. :whistle:
