Did you know that chickens are nearly 70% water and their eggs are approximately 74% water? In order for a chicken to lay a 2oz egg, they need 1.5oz of water for just ONE egg. Needless to say, water is nearly the most essential nutrient. Chickens need to consume twice as much water compared to humans on a relative basis.
