just a quick question..please can a few people answer with different experiences.. i started incubating duck eggs all 15 at the same time..i have a fan operated incubator.. the eggs are now on day 23. they look like some of them are at different stages. some have dehydrated alot and some look like they havent. and some look like they have filled the egg and some still have space.. so my question is if i started incubation for all of the eggs at the same time then why do they look so different?? like days apart?? some of the eggs look almost ready to hatch or have lost alot of fluids and some look small inside and a few look like they filled the egg but havent lost much fluid... any info that would help?
