Well it's not necessarily a Brahma fear, more a shipping fear. Although, I DID have those seven gold laced eggs my first hatch, five of which weren't even fertile and the other two died.
That's so sad!
My first shipped eggs are doing well, and God willing I won't have any problems with them.
My marans and cochins on the other hand...0 on the Cochin's and hard to say with the marans, I have seen some development in at least one, so I'm hopeful!
