My chicken's eggs won't hatch!?

[riceballeater]

I have a Orpington hen that was sitting on six eggs and she sat on the eggs all day only getting off for 10 to 15 min. Well after 28 days not one egg hatched so I waited till 31 day. But still not one egg hatched so I opened one egg and it was rotten.It turned out all the eggs where rotten. so I gave her 3 more eggs and they went rotten too. I have a roster with her all day. she has a nice nesting box, and nice straw but I don't know why her eggs aren't hatching. My roster is like five or four years old though, could it be that my roster may be infertile.

do you know how to tell if an egg is fertile by looking for the bullseye?

yes I do know how but thank you for that.
Just before she wen't broody I had craked a egg to eat and I saw the bullseye. And my other hens eggs are fertile. I know its not just her to because my other hen had gone broody just before her and the samething happend. Could it be that my rooster had gone bad now? or maybe my hens are doing something wrong?

Sounds like your roo may no longer be fertile if this has happened more than once and with different broodys!! I usually get almost a 100% with my own eggs!!

It could just be too darn hot right now and the eggs are going beyond the acceptable temp to incubate?

yeah that is perplexing, other than what you said you checked for the only things could be. the hen is throwing a higher temp and humidity to the eggs or some kind of bacteria causing them to ferment and go bad.

Well it has been really hot here maybe that is it.
Im going to buy a new rooster to put with my hens. If that doesn't work I will probably take my hen and an egg to the vet.
Thank you all so much for all your help.
This is the first time any of my hens has gone broody and none of the eggs hatched.

Well im going to try my best to help her.
Thanks again.

If you can see a bullseye, your rooster is not infertile. And in any case, infertile eggs do not automatically go rotten, there needs to be bacteria present. If I were you, I'd try hatching some eggs in an incubator. Would be interesting to see if they would develop or go rotten. Even with temps being so high that the embryos would die, you still wouldn't expect to have all the eggs automatically go rotten. My bator recently cooked about a dozen fertile duck eggs but all that happened was that they stopped developing, they didn't go rotten. Might be an idea to scrub out your coop and nesting boxes with some kind of disinfectant before you let your hen sit on any more eggs. Might also be an idea to worm and delouse her too. Just in case she's harbouring any nasties that could contribute to a compromised immune system. I think it's most likely just the extra hot weather though...
