I found a nest of Araucana and duck eggs in the duck house today. 16 eggs total - 4 duck eggs and 12 green eggs from one of my little Araucanas that just started laying. The Araucana roo and his two ladies pretty much live with the ducks and hang out with them all day long before returning to chicken coop at dark. She had been laying eggs all over the ground by their pool so I started gathering them and had several in bator before Gustav hit and knocked out our power for a week. They were all fertile and developing. Then suddenly last week, no more eggs on ground so I started trying to find a nest and found one in duck house under a wooden "sofa" that's in there - remains from a child's playhouse. There was a duck sitting on nest for a couple of days so I couldn't see into nest till today. Anyway, look at this huge egg next to one of her other eggs. I put all the eggs in the bator and just candled this one and look - DOUBLE YOLK. I'm hoping for twins. I think the egg is big enough to support two especially since this bird is very small, rumpless and tufted. I can't believe she could even lay an egg this large - she just started laying three weeks ago at the age of 4 months. Of course I don't know how long it's been under the "sofa" in the duck house where I found it. One egg was crushed and a few look like they've gone bad when I candled them. I'm surprised to find duck eggs since my Mallard females aren't even four months old yet. I'll keep everyone posted on the possible "birth" of twins.
