The wyandottes have always eaten game or turkey game when molting. I put lay pellets in a couple of times and they just threw them on the ground. They are very regular layers but they do go need extra oyster shell more than my layers do. For the size of the bird they are quite frugal with the feed.Yes to hatching better. Some think that too much protein will make them lay less.
Roosters are not supposed to have extra calcium--it hurts their kidneys.
