Blossom end rot on tomatoes

Blossom end rot on tomatoes

Please help me, I'm desperate. I'm making a valiant attempt to grow tomatoes but everyone that has come out on my vines so far has ended up with blossom end rot. All 20-some of them. I have mulched them. I don't get the leaves or the blossoms wet. I have egg shells around them. I feed them with powdered or liquid milk weekly. What else do I need to do to make these tomatoes make it!?! Please, anyone, any ideas? I'm about to tear every vine I have out and feed it all to the chickens.
what the heck is that?
