Your puppy is being a puppy, he should be supervised when around the chickens, so that behavior can be corrected instantly. Perferably on leash or a long check line. Give him a sharp tug (he should have a buckle collar on, he is too young for a choker at this stage) and a sharp "leave it" and then as soon as he turns his attention away, instantly praise, lots of good boys, yeah, make it lots of fun!! Consistency is the key, short lessons a couple times a day, maybe only 5-10 minutes each, if you can.
Seven weeks is way to young for a shock collar and I am sure there is a warning on them not to use on dogs that age. You will ruin him if you try it that young. Shock collars have there place, but should be used for dogs that traditional methods don't work for, that are already grown and hard core. They should also be used under the direction of a trainer or someone who knows what they are doing. I have seen more dogs ruined by people who don't have a clue, then helped. Usually the dog has to be put down because it because so aggressive because these idiots shock it for every little thing and with no training to go with it, the dog has no idea why or when the shocks will come next. It makes them nuts!
I have also seen people use it responsibly and have great results, but not at that age, only on adult dogs.
