This is a good topic.....I have a few eggs that are in the 12 to 14 month range. They are single eggs in a container by themselves. Either the rest of their clutch already hatched out or the rest of their clutch went bad. These single eggs still look good. I'm just going to keep them until they hatch or shrivel. I've recently heard from a couple of sources that Ankaramy eggs take a little longer than other locales. Like an average of 12 months. I have several Ankaramy clutches. In one clutch there are over twenty eggs. The clutch was laid six months ago. All except for one look white and at the same stage. This one egg in the clutch has grown much bigger and is colored differently. You can actually see that there is a developing neonate in it. It looks like it is going to hatch out earlier than the rest. This same thing happened with the one Andapa clutch I have. One male and one female hatched out at the end of August. The other eggs are just hanging out in the incubator. They don't look close to hatching yet. It sure makes it hard to plan caging needs when things hatch out like that. I wish I could figure out what causes these differences in hatching times. It can't be just a temperature thing, at least in my case. Thanks for starting this thread. It's an interesting one
