That's because she's not in labor, just close to her due date. All they know is that she should be giving birth soon, but they can't 100% know when because giraffe labors are so quick. So they started the live feed. It's not like she's been having contractions and the baby's feet hanging out for weeks ?.
@samir they've also had the feed cut out due to the storms. I'm sure it'll happen one of those times lol.
