Just finished our third annual hatch in our high school animal science program. Upon doing an "eggtopsy" on the ones which didn't make it , one third of the eighteen eggs set in the incubator had chicks which died in the last few days before hatch because of mal-position. They all had their tails toward the air cell and five had not absorbed their yolk sack. The sixth had, and its egg had been rocking around until hatch day. My students want to know if we are doing something wrong. Is it a problem with the shipping, the incubator, the parent stock or is it just the breaks. Last year, we had a better hatch, but four were backwards and didn't make it out and another two were in poor position, but were helped and made it out ok. They were from the same hatchery as this year's eggs.
