I looked up venomous snakes in Delaware, and found you have only two. The copperhead, and the timber rattlesnake. Just for your info, the rattler is worse to be bitten by than the copperhead. Here is a link showing you what these look like: http://www.preservevenomous.com/Ven...s of Delaware/Venomous_snakes_of_Delaware.htmIts not a Rat Snake, it is a Poisonous "Clock" because during the seasons a mark on its belly goes clockwise, spring 12:00 summer 3:00 fall 6:00 and winter 9:00, a clock snake, it is not a rat snake it will kill your chickens, in the winter one was found dead, they had studied it, and they found recent chicken bone grinds.
Sorry, don't know how to shorten that. And don't feel bad, all areas have different nicknames for snakes. Here, people call gray rats "white oak runners." That took some getting used to for me. Take care, and have a great day!
