I have got 6 months old Great Pyr/Lab mix pup. She is ok with chickens - does not try to grab or chase them - although we have only tried on leash so far. She likes to lay or sit and watch them. But she does not guard them. I.e. she will not necessarily come to look at them if they make alarming sounds and she ignores any wild birds flying above. Does she need to be thought to be more protective and bark at things that don't belong and how, or will it come to her with time?
