Air sack huge on some eggs , but tiny on others on day 11 of incubation.

So im gonna assume they will be fine, they are developing, but wondering if its normal. So here are the details, i have a mixed freeranged flock. I also ordered some fertile eggs and had them shipped. 2 separate packages, one from texas ,one from Florida. Well i candled them and the sacks were destroyed, multiple air pockets, and moved all over the eggs. I let them sit 24 hrs, still never reattached. Well i filled the incubator anyways. So total 44 eggs. 15 from Florida, 14 from texas , 15 from my coop as a control, ( ive personally had a 99% hatch rate from my flocks eggs, surprisingly from a cheap $60 ebay incubator ) anyways, day 10 candled, 5 nogos on Florida, 6 nogos on Texas, 100% development on mine. Cracked them open , and they were completely scrambled, looked like someone took a fork to inside of the eggs, (thak you USPS). Anyways, the 8 eggs i have left from texas, have huge airsacks, like 5 times the size of all the rest, and the development looks like they would be 4 or 5 days behind. The eggs from Florida look no different inside than mine either at this point. Do certain breeds develope differently? And im very sorry for the long winded post.

This has pretty much been my experience with shipped eggs as well. Big and/or saddle shaped air cells and some delayed development. Some of them hatched, but a lot did not. you have better luck than I did!
