Okay...so my neighbor has chickens too and two Shepherds. The dogs roam their yard limited by invisible fencing but their pen is strategically placed next to the chicken coop. Set-up seems to work divinely to deter would-be predators. So...here's my story...with pictures. I have a 9 yr old ginormous 6 second-dozen-donut-eating (box and all) chocolate lab...and I mean ginormous...175 lb - 180 lb solid massiveness. I've had black labs before but this chocolate lab is just huge... NOTHING gets close to us without him alerting us...except for the squirrels...he could care less about the rats with the pretty tails. Not sure how he'll be with live chickens...protect, eat or cower... I say live because he had a squeaky chicken that he just loved. He didn't rip it apart (amazingly) or even destroy it by over-loving it. It was his baby chicken....and he knew the word "chicken" and would fetch his chicken specifically out of his other items of interest when I asked for "chicken".... The protect... Well...one summer day...Dad (the boyfriend) caused a calamity of tremendous proportions...he ran over "chicken" with the riding lawnmower. Little bits of rubbery chicken scattered about...a very sad sight indeed. Puppy was sad... Mom searched high and low for a duplicate rubber chicken with no success. How rare could this rubber chicken be??? I settled on a different style chicken...in hopes to ease my fur baby's sorrow... At first, he loved his new chicken... Then...just moments after above picture was taken....he picked up his new chicken...circled around a bit...found the perfect spot....and the culling commenced... The eat. Now...as ginormous as he is...he is afraid of my little Scottie...who is basically only the size of his head... He tried to sniff her butt...ONCE...and she abruptly did a 180 and gave him the business. He vertically jumped 3 feet in the air and has since kept a cautionary buffer between himself and that little hairball with teeth. The cower. My 5 chickens are confined to a coop and run. At no time do they free range. My question is...do you think my over-grown, couch potato, head-sitting (my head) garbage disposal of a Chocolate Lab strategically place up by the coop would be a good idea to deter would-be predators? Just by his proximity to the coop? @penny1960, I know you have a donut-loving lab as well...thoughts?
