HELLO!
Is that an indigo snake, a black racer, or a very dark kingsnake? Hmmm...
It’s an Eastern Rat Snake.

Great ratters & mousers. Very good at getting into chicken coops & eating eggs. My SIL saw one that had caught a baby bunny & was constricting it to death. The only time I would kill them was when I found one in the chicken coop - you can remove them & they just come back. We had one in the coop with a scar on its back so identifiable - SIL took it down the road & it was back & headed for the coop 3 days later.
Funny story - we have a lake cabin that is very rustic. It is not a 4-season house - family uses it late spring to late fall until the water needs to be turned off. There are always mice over the winter. My brother was making coffee one morning when a movement on the counter caught his eye - it was a Rat snake, coming out from behind the microwave! It had found a way in the house to hunt mice. If my SIL or some of the other women guests had seen that snake first, there probably would have been a ‘scream fest’ & potentially some fainting. My brother wrangled the snake into a trash can (a 3 footer so not a huge snake) & released it. He took pics to show the ladies, who were horrified :-)
