Why do they pip at the wrong end?

Last year I hatched chicks in my homemade incubator with pretty much no problems. This year I lost all but 1 of 50 eggs. I did have some humidity issues the first time. Now that's all fixed. Humidity is where it should be and in on day 22. About 2 dozen eggs in and they all looked good on day 18. Even took a quick candle this morning to make sure they were okay and the couple I grabbed looked good. Could see them trying to pip. Now my problem is 3 have pipped but they have ALL pipped at the wrong end!! I had one last time do this too. I had them in egg cartons but took them out when I saw the first one. Any idea why they do this?? I'm pretty sure one if them won't make it because I see some blood. It's just really odd.

 

So to add to this, I have ended up with 4 Cochin/Silkie cross and 1 olive egger out of 2 dozen eggs. A couple other eggs tried to hatch but didn't make it. I still have a few left and in giving them untill Sunday night, which will be day 26. Every one of them has pipped at the wrong end?!?? Why? Maybe I need an automatic turner? I have eggs coming at the begging of April so if anyone has any ideas, I'm all ears. Thanks!

 

Thanks.

I thought I was doing everything right. My first hatches turned out okay. I know that my previuos hatch was bad because I couldn't keep the humidity up.

This time I stored the eggs pointy side down for no longer than 7 days. I put a book under one side at a time while collecting eggs and moved it 3 times a day. Once in teh incubator I turned them 3 times a day and the humidity stayed between 35%-40% and the temp was 99-100.

On day 18 I bumped the humidity up to between 65%-75% with them temp staying the same. I also stopped turning the eggs.

Any ideas on what I might be doing wrong? Is my humidity okay? Or is it to high or to low? I welcome any help. These were suppose to be sold but my state requires that 6 must be sold at a time unless they are over 8 weeks old. I had people interested in some but I guess not this time.

 

I'm pretty sure the humidity was the same before. Although it was during the summer last time. This time it's winter so I'm not sure if it is the weather or not. I did candle and everything seemed just fine. Even on day 18. There was plenty of movement.

My hens are all just under a year old. And the last batch had eggs that I purchased through someone here.

I'm pretty sure they are getting everything they need. They get plenty of layer feed with scratch and BOSS. It's fermented feed. They also get treats two to three times a week.

And I'm not at a high altitude either. I'm just confused. This is a homemade incubator too.

Thanks for any help and ideas.

 

Thanks for trying. I will just keep trying.
