There are a few methods out there for poaching eggs to try to keep them together/neat - eg some suggest making a slight whirlpool in the water and adding the egg to the middle. Others cook the egg in a little cling wrap/film twisted bundle, and yet others add a little vinegar to the water. Personally, I don't like the vinegar method as I feel you taste it, and I always have mixed success with the others. But do as you prefer/know works for you.
