hatching process? Eggs are for human consumption or for hatching into broiler (meat) chickens. Medical labs (and military bio-warfare depts) buy eggs by the ton for growing viruses and whatnot in them, since the egg has all the necessary nutrients. I think this is all they are referring to, not any irrelevant hatching process (since no one will be hatching the eggs). As sibsab says, the difference between the eggs are that the SPFs are "specific pathogen free" and the commercial broiler eggs are not so certified, so may contain pathogens. The safety trials are about the vaccine, not the 'hatching process'.

# sibsab The Question is ...What are commercial Broil eggs?
answer= a hatching process which is a commercial operation/business

Sabine Akabayov, PhD Jan 23, 2009:

@Gary: both kinds are from a broiler. The difference is the environment, one is pathogen-free (SPF eggs) and one is a commercial setting, where the chickens/eggs might be exposed to certain diseses

a way they are hatched

Thanks, Gary. The context of this phrase is:

We will conduct safety trials with these lab made vaccines, rcNDV and rcNDV-VP2, exactly follow Alan’ protocol for Safety test for in ovo administered rNDV vaccine, in both SPF eggs and commercial broil eggs.

looks like you place them in a casserole pot and place the pot in water and put them in the oven

broil eggs look like "poached eggs" cooked out of the shell in shallow water
