I have two coops one gets 8 eggs a day and the other gets about 3 eggs a day recently I've only been getting 3 eggs a day from one and 1 egg a week from the other I saw two snakes yesterday both were rat snake ( one might have been a black racer ) but one was about 4 feet long and the other was about 2 and we also have a lot of skunks around here. What could it be?
