Looks good to me. I usually wait until 7 - 9 days to candle mine and refrain from handling the eggs as much as possible. Remember that darker color eggs are hard to see so sometimes you have to go with luck.
I candle a few of my eggs every couple of days. I checked them day 5 and tossed any that were obvious that nothing was going on inside. I compared them to an egg from the store. For someone that isn't very experienced I suggest either day 9 check them look for veins. If there are veins it's good. If not toss it. Or just incubate all eggs until either they hatch or dont hatch. But be careful doing that. I've had an egg blow up on me this year (it was gross)
sorry i messed up lol the 1st egg is at 8 days...the 2nd egg is at 3 days....my hen was setting and for the past 3 day when i go to feed the other's she has been off the nest and i watch her through out the day out my window and she has stopped setting and has started laying again....she is my only brown egg layer at the moment and i have been finding them the past 3 day and she was on day 5 when she stopped...so i brong her eggs in with the other's and candled them and all of them seem to be fine but egg #1 i am to believe is a blood ring...the vein's are not visable and there is a thick blood ring around the embryo now.....And (sweet lil baby ) i checked the eggs under my hen and there was a bad oder coming from under her and i smelled of all her eggs and found MR.STINKY......sheww did it stink ! i took it and busted it and it was so nastey......but my hen has been through a lot in these past few week's....we had a bad storm and it messed there coop up and she was setting good then and it broke all of her eggs but one.....then she started to layed more eggs got 10 and then started to set...i went down to feed and some how an owl had gotten in there and killed my rooster and he was still trapped in there and we got him out and still could not find out how he got in there but he has not been back since.....but in the mix of all that her eggs got broken again....and she done had it in her head that she was going to hatch some babies so she started laying 2 eggs a day anf before i knew it she had 10 and was setting and would not get off her nest...and now she just lays in the run all day and will not go in the coop till night and she sleeps on a roost instead of nest box were she used to.....DO YOU THINK SHE IS RUINED NOW BECAUSE OF ALL THAT HAS HAPPENED TO HER ?
