I am very new to pigeons, and I have two that are nesting. The female (hen?) has laid two eggs, and sort of appears to be sitting on them. But since I hadn't expected eggs, they don't have a proper nest and the eggs are sort of getting rolled around in their little house. What I need to know is, should I set up something for a nest, and if so, what are some ideas on what I should use? If I move her eggs and put them in a different container, will they stop sitting on them? Should I raise the protein level in their feed or anything? Thanks!
