I am new to this forum but it has already proven to be very helpful. I lost 2 small hens to a rat snake over a month ago. I thought my coupe was pretty tight but apparently not for the likes of snakes. We added some extra security to the coupe and left one of their eggs in there as bait. There were no signs of a snake for 2 weeks so I felt as though our improvements were successful and it was safe for more hens. I purchased 3 young hens about 6-8weeks old and introduced them to their new home. Things were quiet the 1st week or so. Anytime I saw a rat or corn snake on our property I would relocate it to what i thought was a safe distance. This past week has turned into a nightmare. I have seen a total of 6 snakes in less than 1 week. Saturday evening I was alerted by the hens and ran out to check on them. I was horrified to find the Barred rock on the ground with snake coiled all around her and squeezing the last breath out of her. Thank god I arrived in time and as of today she seems to be doing well. This was not a large snake by any means and I would have never deemed him to be a threat. I took the suggestion of a recent post and sealed all cracks with spray foam sealant and am hoping this keeps them out. I am so frightened for them. Again! Sunday night when I went to check on them all looked fine until I gazed up and spotted a huge rat snake on top of their coupe looking for a way to get in. I am a nervous wreck and would appreciate any suggestions in keeping the snakes away. I have horses too so I am limited as to what pesticide i can use around the coupe.
