Guineas will often lay in a communal nest until the clutch reaches a size that triggers their desire to brood. It is not uncommon for guineas to lay clutches of 20 eggs or more before going broody. It is also not uncommon for communal nests to reach fifty to sixty eggs with multiple hens setting on the nest.I've been removing the eggs since no one is sitting on them. Should I leave them there? I would think if the eggs are cold, they're not going to hatch anyway. I know they are not good mom's, but they don't even sit on them!!
If you want your guinea hens to continue using their nest, be sure that you leave a fake egg or more in the nest. Guinea hens have been known to abandon a nest that is being disturbed.
