Ok so this is my first time incubating. A few months ago I purchased an incubator, but I was too nervous to try it in case I did something wrong so I just brought chicks. I purchased more chicks 5 days ago and the lady gave me 4 araucana eggs. I decided to put them in the incubator. I can't believe it but I candled them today (day 4) and I can see veins in one of them! I am soooo excited. The others are a slightly darker shade so hard to see. I make out a two toned dark ring. It hard to explain. I think I can see a couple of tiny viens in one of the dark rings. But the other 2 nothing. All I can say is they all look very different to a shop brought egg. I hope this works out, I'd love to see a chick hatch! When should i candle again so i can be sure they are all developing?
