So we just had a 9 day vacation. Had some friends take care of the animals for us. Went out to the coop and Candled a few eggs and saw little veins in about 3 of them. I know nothing about hatching eggs, so I am glad my hen is taking care of this for me. I guess I'll let nature run its course. I took out a few eggs that had no veins, but unsure about cooking them for us. (May crack them and cook them for the hens). How long does this take? I saw a few candeling pics and the ones here are about 3 days. Thanks for any advise in advance!
