I have two call ducks, bonnie and clyde. We would like bonnie to lay eggs now that it's warmer (she laid multiple eggs during the winter, but it was 30 degrees and below so any fertilized eggs died) and then we'll bring them in and incubate them. we switched their food to a mix of more powdery stuff with no corn in it that the guy at the ranch store said had more protein and would help her lay eggs. do you guys think that will actually help? what can we do to help her lay eggs?
