Somethings wrong

Well there's defenitly something wrong with the fertility of my little La Bresse flock.

Just hatched 1 from 9 eggs while my IG eggs hatched 8 from 10.

Last hatch I hatched 4 from 9 but 2 of them had something wrong with them and didn't last long.

Now I am unsure of the age of the cock bird so maybe it's time for a replacement, the hens are about 3-4 years old and lay really well.

Any ideas ?

What are you feeding them? You might find you have to up the protein levels.

There on standard layers pellets and some scratch corn in the afternoon

I think I need to reduce the number of hens he has which is 11 to about 5
Or give him the chop and keep a young male from my chicks to use on the older hens next year.
Or bring in some new blood

Were all his eggs full, or empty?

Only 1 clear the others were dis

Jaycee has mentioned protein and I think that's something worth looking at.
I take it that the eggs were in an incubator rather than under a broody? Otherwise I'd say luck of the draw and a poor broody.

Yes all in the Incy and the Indian Game that were in with them had a good hatch.

When I cracked the eggs open they were fully formed but dead in shell  

I'm not sure how old the cock bird is ?
And the hens look different ages so shouldn't b too closely related.

If i try another hatch I will reduce his hens, but I don't like hatching any later than now really.

If you go back a year or two, you'll recall the problems that I had hatching Welsummers, while the LS that I had in with them were hatching for fun. Maybe your birds are simply a tricky breed to hatch? Perhaps they need more humidity than IG to hatch successfully?

They are very much the "New thing" in the USA (even though they have been around about 500 years)  
So I have been looking on a forum over there.
And the word is that they are generally very virile and easy to hatch  

Just not for me, ha

also Hatchability Problem Analysis by H R Wilson is useful in identifying causes.
