HOW TO HATCH THIN SHELLED EGGS?

[sherpagirl]

Does anyone have any information on how to hatch thin shelled eggs from older hens?

Some ideas I have heard:

1) Use higher humidity during incubation

2) Partially cover the egg with beeswax

Does anyone have experience or ideas?

Thank-you,

Donna

I've hatched thin shelled /porous eggs or eggs with shell defects (lines and ridges) from my old white leghorn girls. Usually just keep a really close eye on the air cells and adjust the humidity by how they are doing. I do usually wind up splitting them between at least two incubators because the air cells develop at different rates and have to keep the humidity different. I usually incubate around 40-45%, some of these I usually wind up doing more at 50-60%. Still hatch at 65-70% The hatch% tends to be lower than normal on these, but the chicks that do hatch seem fine. Never tried covering the shells with anything.
