Sorry, to tell you this, but that Lab mix is never going to stop killing chickens if he gets a chance. Only option is to keep them forever seperated with something he can NEVER get thru. The lab instinct is too strong even with trained dogs. Sadly, I just had to drop mind permanantly, about a month ago, and gave away her daughter. Electric fences didnt work, shock collar,pfft, only thing that worked and that was putting her down
