More often than not you see successes from PH's on this and other forums for two reasons:
1) Most of the animals are 66% or at a minimum, 50% PH which means that the majority of the time - the odds work out.
2) People don't often post when they miss on the odds which makes the successes seem disproportionately represented.
As Amie said, you could have just had really bad odds, but it's also equally likely (or perhaps more likely) that the "PH" part just didn't work out.
Sorry to hear you invested several years into this project to have it not work out like you had hoped. Unfortunately, that's the reality of going with PH's. PH's can be a great, inexpensive way to get into a project, but unfortunately it can also leave you highly disappointed and you have to be prepared for that outcome going in.
