I had read on several sites, that if you had a snake problem, place bird netting loosely around the outside of you coop/run and it would 'catch the snakes. WELL, it works! A few weeks I pulled out the bird netting I use on my blueberries and left it on the back of our big old truck... Got called away from the farm for a few hours, while I was gone the tornado blew thru and it blew away my netting.. Looked around for it but could find it.. Figured it was gone... Yesterday, we were working in the garden and our old Dachshunds started barking and being very angry about something ==which ususally means a snake.. Dh went to ck on them... Sure enough it was snakes---4 huge snakes. three black snakes and a copperhead--WRAPPED up in the netting. Two of the black snakes were released, the other was dead and the copperhead "died".. We had to throw the netting away--dh cut it up to release the snakes.. But when I get chicks, I will have netting around the brooder... Now I know it really works..
