At first I was full of optimism about getting our 11 year old dog used to our pullets. Training was going well.. He was relaxed even sleeping while they were in the same yard and he was on the lead. Then one chicken found its way into his fenced yard and we found it dead. Further fencing and further separation has ensued.. all peaceful. Will I ever train him not to go for them? Locking everyone away from each other was never really my ideal.
