Mine is a hunting breed, but a lady who has our same breed (4 so far including two from me) tends to free range laying flock, and the dogs come with her to work and hunt out the eggs laid out of the coops, and help herd them up to get them to go to bed.
Dogs need to be proofed with any livestock and taught they are not allowed to chase, under control, in fact all gundogs are taught to leave fowl and rabbits by being exposed to them in training and taught to leave them alone.
My 'townie' reared dogs no doubt would get very excited and chase and kill chickens as they have never encountered them. So my lot are strictly on lead on the rare occasions we are near livestock.
