Chris - welcome to the board
So sorry to hear of your loss, but glad to see you have come to terms with what they bring to our lives and that you're looking for a cocker.
At two weeks old you won't be able to see which is the best pup, it's more likely to be around 6 - 8 weeks when their personality starts to come through. You want a pup that doesn't come charging to the front nor do you want one that stays behind - one that plays well with it's siblings and is happy to have a cuddle is likely to be a well balanced pup.
The one that comes to the front first can be a problem in that he is too sure of himself(or her of course;) ) one that hangs back might be a bit more nervy and have problems of that nature.
All that is only a rough rule of thumb and a guide and neither may end up to be true - there are soo many factors that influence how your pup will be not least the breeding. If you can see relatives and get a feel for their temperament - that will help.
From my experience, if your puppy is home reared, by that I mean raised in the house rather than in a kennel kept away from the family, then you are likely to have a better socialised puppy - especially to household noises and activity.
Good luck with your puppy - this is going to be such an exciting time for you.
