Not fertile?

[HeartsHolly17]

I purchased eggs from a local farmer who hatches eggs from his hens all the time. I put them in my incubator and I’ve been turning them four times a day and the temp is firmly at 100°F. It’s the third day I’ve had the eggs and today I checked on one of the leghorn eggs I have and it doesn’t look like anything is growing inside. Is it too early to tell? Or is this egg infertile? It’s my first time incubating so I’m stressed to the max and I’m probably just overreacting- but I would like to know if this egg isn’t right

Doesn't look like anything is developing to me. You could wait a few days just to be on the safe side.

It is too early. Wait until day 10.

You would have to wait until day 7/8 to be able to tell if it is developing. I wish you luck!
