Dying chicks-Roo problem?

[smith2]

About a year ago I got a BR roos that is beautiful from a woman in my area. I have tried to hatch eggs from this roo and 5 hens that are kept with him all the time. The eggs start developing and then die at about 9-10 days of age. Could this be a rooster problem? I know it is not the incubator because everything else is hatching just fine. These are the only eggs not hatching? Could anyone give me advice or help or have heard of this before related to rooster fertility?

Need a little more information.
How many clutches have you set of his eggs?
How many eggs do you estimate in total?
Do they all quit in the second week time frame?

The number has to do with establishing that it is a consistent problem and not something like that coop got to cold or something like that.
Knowing the time frame in which the failure happens can help you try and determine at just what point of development the chicks are lacking what they need.
You would want to start looking at nutrition. I would not suspect the Rooster as the most likely problem. It could be the hens and something that effects all of them.
Other eggs hatching in the same incubator does tell you it is not an incubation problem. but still does not point to the rooster. Could it be that you have a lethal gene situation?
I saw an egg development link the other day that explained just what is going on at each stage of development of the embryo. What nutrients are needed at that stage etc.

I have set over 50 of these eggs in three different batches about 2 weeks apart, and many of them are not even fertile. Of the ones that start developing, they seem to die soon or about half way through the hatch. I have never had this problem before. I really don't think it is nutritional. I give them 22% layer pellets, vitamins, and DE. The others get the same stuff and they are all hatching just fine. He does jump the hens, but I think he may have a sperm quality problem.
