It's not. Juice is 14 lines up and two columns to the left of that red square. It might've been a bug that messed up the save and failed to count the egg. That, or Lewis stole the egg for himself, whichever theory one subscribes to.
I vaguely remember the ostrich egg not being counted as it should have been. Your best bet is to ship it again (assuming you put the first one in an incubator to get ostriches...)
Depends on whether they tried to ship their first egg, or hatched it and sold the first egg their ostrich laid. They mentioned having shipped an ostrich egg before. Getting a second egg in the first case would be a bit tricky but not impossible. The second case, just wait a week.
