Not sure if it helps or not but we have had more than our fair share of snakes,I cant stand them.We have both copperheads,black snakes as well as garden and other posenious snakes,either way..."they are outta here."Im so thankful they were not in the coop at the same time I was,OM~GG I would have made a mes of myself..lol Sorry to the snake lovers but if they were w/in range and I was uncertain of the kind of snake,they were gone.If we knew it was a garden,my son relocated it. Our girls have a attached run n are locked in at night.I keep the feed in coop n never outside.I do put cold watermelon n treats in play yard in early am n clean up any mess to not attract critters.For the snakes I have used......
Coffee cans with holes..put lid on after dumping box of moth balls in them,refresh them every few weeks. I sit numerous cans ard outside of coop/playyard.(wash cans well w/soap 1st..
***Dont sit moth balls or anything w/strong oder too close to girls,theyre little lungs dont like strong odors!
** Snakes love coffee n coffee grounds~if u r a big coffee drinker or compost your grounds..."STOP" if you have a snake issue..Dont dump your coffee in the yard or use grounds in outside plants or compost..
** ALSO, cinnamon n cloves are a deterrant..I bought several big bottles of cinnamon n ground cloves n sprinkled it ard the play yard/coop..Its recommended to use clove oil n cinnamon oil,but I couldnt find it..Yhis has help us,hope it has been helpful advice..
