I ordered chicken hatching eggs off eBay at the end of last month. They were delayed two weeks. I put them into the incubator the day I got them, last Wednesday, and candled today. I don’t see prominent veining in any of them except four. I didn’t have high hopes since they were delayed so long. But two look like the one pictured. The other two look like they’re maybe a week a long. How far a long is the one pictured and when should I stop turning it? The farm I ordered from says they eggs were picked fresh and should have been to me in three days.
