How do you know if they are fertilized?

yes that is signs of an embryo probably 3 or 4 days into development.

Next time you want to check fertility, check eggs your going to be eating. If you have eggs under a hen for hatching or in a bator, wait till day 7-10 and then candle them with a bright little flashlight in a dark room, you will see a dark spot and veins really well by day 7.

Leave any others your trying to incubate alone until then, and then candle them with a light in a dark room, quickly then pop them back in (or under your broody)

lol, because i am a first time egg mommy with eggs from my own hens and have absolutely no patience sourland!!! hehe... i can definitely say that i feel really bad about murdering a potential chicky, and will never be trying that again!!!!!

but at least now i know my roo is doing his job, even is he does hate me, i guess he can stay...

all eggs i have are in the incubator, and it just decided to drop back down into the 30s so i doubt i'll be getting anymore anytime soon... otherwise i would have check without cracking one of those.

i think this will end up being more addicting then going a picking out little 3 day old ones out from the feed stores! ... this could be bad.... LOL

Also, is there a way to guess how many are actually fertilized? i opened 2 and only one was, the other was nothing, same hen too.

Wait and candle them or see how many hatch. Whatever you do, stop messing with them except to turn them or candle them!

Unfortunatley it was fertile there are other threads that show eggs thru all 21 days
