Has anyone ever used a bitter spray on your chickens to prevent a predator attack. My dog attacked my girls the other day. None died, yet, but one looks like she may today. I am wondering that along with training him to be around the chickens without interest if bitter spray would be a good deterrent? I am going to use a shock collar along with training. I want him to look at the chickens as an unappealing target. Thank you for all your great comments on this site. I look forward to your answers. God bless.
