I've got 13 guinea eggs and 11 barred rock eggs in my homemade bator. Today is day 10 on the guinea eggs, day 4 on the BR's. I know it's early, but I candled them today just to see what was going on. 4 of the guinea eggs are clear, should I go ahead and throw them out? 1 of the guinea eggs I saw what I think is a blood ring, the lower edge of the dark mass had blood along it anyway. All the BR eggs look viable, none are clear I'm going to use a brighter light (gotta run get batteries) and take another look at the one with the blood, but if it is blood I'm seeing should I throw it out too?
That dark mass with the blood around the bottom is likely a chick with the veins that are encircling the egg. I almost tossed one of those because I thought it was a blood ring but changed my mind and hatched out a beautiful Americana chick!! Don't toss it yet!!
