I can also say the video is 100% real. A friend of mine was working there when those hatched out and told me about it.
Also, it is a bad idea to remove babies from their egg, but if you notice all the person in the video is doing is pulling them out a little bit for the video. They were not completely removed. Also, the person pulling them out of the egg is probably the owner, who has probably hatched out well over 2000 retics. So, I'm sure he knows the limits better than the average person.
