None of mine hatched

That totally bites
I REALLY hope I get a decent hatch from my shipped Am eggs.
It turns out the pair of bantam wheaten Ams that I have suck genetically.
-Their eggs don't like hatching
- of the THREE i have managed to hatch out this year (maybe set 20 eggs), two have funky beaks (not cross beak, but the top beak is a bit of an arch, doesn't mess with the ability to eat, but clearly not right), and, of the three that hatched one (the only one with a good beak) is half the size of the one that hatched with it. I have been wondering why it hasn't died. It almost started to die, andI fed it fish oil for two days, and it perked up again.
- the rooster has a horrid crow
