When is it advisable to blow hatching eggs? Do I wait a week, two weeks... when is it safe to say that the little eggs is just not fertile?

Id like to know for..

Pheasants...
Chickens...
Turkeys...

I know that for pheasant and turkeys, its 28 days hatch time... For chickens its 21 days hatch time.
 
Are you wanting to blow eggs that have already been started on incubation?? I wouldn't do that -

An egg that hasn't been incubated is fine to blow out at any time...

You can tell an egg is fertile by a small 'bulls eye' white spot on the egg. You can crack it open to tell. I think there is a thread on here that will teach you the difference in fertile and non fertile eggs.

yes... I wanna know when its safe to remove eggs from the incubator. For example, I would not want unfertile eggs to get incubated for the entrire 21 or 28 days and then explode or crack before the due date and leave a mess everywhere...

Or are you saying that it is safe to incubate unfertile eggs up until the time they are moved into the hatcher?
 
Yes,

When is it safe to say... this is an infertile egg by candeling and then I remove it from the incubator...

Sorry I was not much clearer.. its been a long day and I forgot that people cant read my mind...

I probably wouldn't do that but I guess you can if they haven't been 'cooked' for too long

It might be stinky and smelly if they have already started incubation and aren't fertile...
 
I think the confusion is over the word "blow"--correct me if I'm wrong, but I think the OP just means that he wants to know if he can throw them away. And I think some of the responses are reading it to mean he wants to blow the insides out while preserving the shell in tact--like you might do for an easter egg you wanted to decorate and then keep. But which, of course, you wouldn't want to try and do for a rotten partially developed egg.

Is that clearer? Or did I just muddy the issue further?

And, by the way, once you know what you're looking for, you should be able to tell by Day 7 if the eggs are fertile. If I'm not sure, I wait another few days and check again. If I have one or two that are doubtful, I set them aside in the incubator (if there's room) and keep an extra watchful eye on them. I smell them every day and watch for oozing--if they start to stink or ooze, I know it's time to toss them. Also, I check every few days for development--if they've made no progress in a week, I toss them.
