All you have to do is list the auction that you want and what you want to bid. There are two sets of blue laced red wyandottes on the thread right now, so click on the one that you want to bid on. When you get to the original post, you will see on the left hand side who is offering the eggs. Then hit reply and say something like, "I'll bid $1 million on schmmems apple pie (but put the real name and the real birds that you are bidding on). It's really simple, but understand that what you bid is what you pay. We do not have an automated bid increment like the BST section. So if you only want to bid the reserve, only bid the reserve.
I've gotten some really nice eggs from this thread, and the first batch is due to hatch this weekend. Great sellers, great eggs, great deals!
