I find that my percentage is around 33.....I think it should be better. Is average around 50-75?
Just adding for accuracy if anyone finds this post like I did. No the official hatch rate does not include those that developed but *didn’t* hatch. And if she had helped the one that pipped but didn’t zip, it wouldn’t have been strong enough to even live. I’ve helped numerous chicks that even have zipped… only ever had one survive and it was not a healthy chicken. Don’t help them, I tell myself everyone I won’t help them but I convince myself they got vacuum trapped when I took the other chicks out…. No no no they won’t survive. 😓It depends on how you calculate the hatch rate too. I can't remember the official formal definition. Somehow you don't count the ones that don't start to develop. Maybe someone who knows the correct way to calcualte it can explain the official way to do it. I'm pretty sure we don't all calculate hatch rate the same way.
There is no real average I know of. The way I look at it, if 70% of the eggs I set from my flock hatch, I'm doing OK. Not great, but OK. I always get a few that don't develop and I practically always get some that develop but don't hatch. For example, out of my last hatch, I set 18 eggs. Two did not develop at all and two developed but did not hatch. So I got 14/18 or 78% of the eggs I set and 14/16 that developed or 87.5%. To me, my hatch rate was 78% but officially, I believe it was 87.5%. I had one that pipped but did not zip. If I had chosen to help it, my hatch rate may have been even higher, but if they can't hatch without help, I don't want them in my flock and passing down those genes.
I have not hatched shipped eggs so I can't compare with those but I'd have pretty low expectations.
Do you analyze your unhatched eggs to see why they don't hatch? If you are consistently gettting 33% from your own eggs or shipped eggs, no matter how you calculate it, you have room for improvement.
