I have 9 guinea hens and only get 2 eggs a day. Is there something wrong with their food? They are currently on layer mash with mixed grains and pellets in it. 2 hens are turning three years old, 6 are almost two years old and the youngest will be one in January. I know the youngest one is laying. Some of the others feel heavy like they're laying but we don't get enough eggs. I've looked all over the yard for a nest and found none. Sometimes they go to lay an egg but no egg comes out.
