well, if you move them to an unprepared nest, then the female my ignore them or destroy them. if it is absolutely necessary that you move them, then put in a prepared nest box ASAP. she accepts it, then good for you.
maybe, depending on the size of the feeding tray, you could put it inside of a nest, and then remove it when the female is accustomed to the nest. is she sitting on the eggs constantly, and is she aggressive?

do canaries nest in boxes? or just plain nests?

Just open nests, apparently: http://www.rockportroost.com/2canarynests.html

I recently got an 'experienced' female for my male canary. She had already raised a couple of clutches. Well, the first thing she did was to build her nest in hertheir food cup, even though I placed a nest in their cage. After she laid her eggs, she became really violent toward my male, and I had to remove him. When it turned out the eggs were infertile, I put them back together. She promptly made another nest, and again in their food cup. This time I placed her in the separate cage (the cage was, after all, his originally). Although they hadn't bred, she laid a total of 7 eggs. He sings to her, and she contentedly sits on her 7 infertile eggs. In the spring, I'll put them together to breed, and then separate them so she can lay her eggs...in her food cup :o)
