Eeeewwwww...I'd be buying my eggs from the store now! Hope you find the other one that's getting in the coop. He does look like the water snakes we see at the lake, but I've never seen one that big before! he must love eggs!
I have a cardinal that strikes a mirror on my fence all day...every day.... I have to clean the mirror at the top from all the whitish stuff on it. I found a 5 ft rubber black snake and wrapped it around the limbs of a bush in front of the mirror. No more cardinal so far. But the other day, we heard the blue jays just screeching up a fuss out back. After a while, I walked out to find not only the jays, but other birds had joined in....dive bombing the rubber snake. Quite a sight to see. All's quiet now. No cardinal, no other birds....and I hope I won't have to clean the mirror again for a while.
