I spotted a brown snake in the chooks' run. I was only a half metre away from it before it went slithering under the coop. I pulled up all the boards I could to try to find the snake but with no luck. I did, however, find a rat skull. Do snakes spit up their prey's bones by chance? If so, that might mean that the snake has been here for a while and I didn't know it o.o; I don't know what to do about it. Right now my chooks are safe in my bathroom Can anyone tell me what I should do? Or if there is anything I can do?
