Last night i discovered (and safetly relocated to my garden area) a 4 1/2' Texas rat snake in one of my chicken nest boxes. While i don't mind the snakes and welcome them to keep my mice/rat population at bay i'm concerned with them being in my chicken coop and have a question.....
I have bantam chickens and i'm curious if a rat snake will leave them alone knowing they're too big to eat, or might it make the attempt by killing a hen attempting to eat it then realizing it's too big? I'm envisioning coming out to a slobbery dead chicken here.
Next question. If it's possible my hens are in danger, i'd like to keep them out and have heard a sprinkling of lime around the perimeter of the coop will keep the snakes out. Is this true or an old wive's tale?
Thank you so much for any help!
