BOTH!!! You can post eggs or birds either one. You just have to watch on shipping birds & make sure you have any paperwork necessary for your state or the state you are shipping to. Local pick-up is WAY easier for birds.Thanks for leading me to the right part of the BST. Now, if I can convence my son to let me sell some of our hatches, we can list them on there. Wow! Do ya'll do that w/ your chicks or eggs?
