More questions I than answers

does anyone know what causes the membrane under the shell to be very tough almost like leather can to high humidity cause this or is it the hen

 

[frenchiegirl21]

From what I understand most membrane problems come from too low a humidity. Were these hatched by a broody or in an incubator?

 

[chickens really]

I was also told it is caused by the humidity being too low.......Hope that helps your situation?

Sorry so late responding been busy anyway humidity has been at around 65 percent throughout incubation

 

[frenchiegirl21]

So the humidity needs to be between 25 and 40 for the first 18 days of incubation and then raised to 70+% for the final three days. Hopefully this information will help you on your next hatch! Good luck!

I am no expert.....temp should be at 99.8
Humidity the first 18 days at 45 to 55% till day 18, then 55 to 65% at lock down till hatch......




Cheers!

When should I open the vents for the oxygen

 

[chickens really]

You can open the vent during or after the hatch if to much humidity is building up in the incubator....what incubator do you have?

I don't fret on humidity. As long as it doesn't go below 20 percent.

If it does I just add a little water.

I keep both vent plugs out of my incubators all the time during incubation and hatch.

When it time for lock down I raise the humidity to 70 plus.

This is what I found works the best for me.

I have quail hatching out right now. So far I think 40 are out. And will have chicken eggs hatching this weekend.

Hope this might help.

Good luck with your hatches

Thanks the reason I am concerned is that I am only getting less than half to hatch they die in shell at almost time to hatch I have checked the eggs and the chicks are like mommies all dried out my humidity usually stays around 50 percent then up to 65 70 percent
