Here's the link to my hatch-a-long thread.
Wow! Older then 10 days...?! Whoa.... Okay, so I'll chuck them in the fridge for 1 week.
Edit: Now I've thought about it....maybe for 4 days. (In the fridge.)
Okay, just to get things straight;
How long do I put the eggs in the fridge?
How cold does it need to be in the fridge?
How long do the eggs need to settle?
I've got a hen that I'm going to breed. I just have to get her to lay enough eggs...
Okay, but that doesn't make them reptiles. Just because they were related to a reptile millions of years ago, doesn't make them a retile now.
This is just my opinion.
So about half a week after the eggs have been laid, but the eggs in the fridge at 7.2 C (45 F) for a week, then let 'settle' for half a day (?) Then chuck 'em in the incubator?
