If they lay eggs in the wet season, how do eggs survive considering they lay them in the bush. Are the eggs waterproof ?
most guineafowls especially the wild guineas mainly breed during the wet season, it is not that their eggs love rain to develop, the female need protein which appears during the wet season. So guineas eggs are very hard shelled and are strong enough to tolerate heavy rainfall, although they may be washed away.
