I agree.... I've seen the videos!! lol I was watching a bunch last night, on how to help get air to a baby chick before it dies, if it can't get into the air sac, due to the saddled sacs. I was worried because of not having good air cells in these shipped eggs, that neither would make it.It can be very difficult to know when to assist, and quite often it doesn't end well.
I didn't worry about this in my eggs that we hatched from our own chicken.
I lost 4/6 fertile eggs in the first week to blood rings, out of the 2 that made it to lock down, neither of the air sacs were in good shape...leaving me with concerns on how to improve viability, I did all the steps, except knowing how to assist if they couldn't get to the air sac... so I started learning, just in case. I would hate to lose a chick that was otherwise healthy, simply because shipping screwed up it's airsac.
