Sebas, why did you say that? I need to know.
Now I am wondering about wondering about wondering about hatching. I used to lay the eggs flat, as the trays were designed for in my sportsman. Have an old sportsman that has trays designed for goose and emu eggs. No option to stand the eggs up, like in the trays for the other models of sportsmans. But....I thought that it was easier for the first 18 days to incubate the eggs in egg cartons, rather than strapping the eggs in laying on their sides. Just made easier. But I use carboard egg trays. Now wondering that is not good.
I got to wondering why you said that Sebas. And I came up with a thought. With incubating the eggs in a cardboard egg carton, I wonder if the humidity is being sucked from the inside of the egg into the cardboard egg carton. I wonder if I need to get those eggs out of the cardboard egg carton. Not sure what I would do with them. Maybe just lay flat like I used to hatch. Now wondering if that may be a reason why my hatches have not been as good as they used to be. Darn. I wonder too much about wondering about stuff. I know that.
Hmmmmm...I need to candle a whack of eggs today, and I think I am going to take them out of the cardboard egg cartons and lay them flat in the tray, just like I used to.
Jonny. Your question I will address. When the eggs go to the bottom of the incubator, I lay them on their side. Just like how the eggs are hatched below the belly of a hen. And I don't think the other chicks treating the eggs like soccer balls makes any difference in the hatching. The beak of the chick by that time is already into the air sac and most of the liquid is gone that was inside the egg, isn't it? Maybe I am wrong, but I don't think so. Comments.... Have an awesome day, CynthiaM.
