Day 7...no veins, no embryo...what's wrong?

[shelleyb1969]

Being rather new at hatching eggs, I've just had an experience that I haven't found any info about on BYC. Is it possible for FERTILE eggs, upon candling at day 6, to have no embryonic development and no veins/blood vessels? The yolk themselves are intact, as I opened them to check them out on day 7. They look like a perfectly normal egg on the inside, no blood rings, nothing abnormal...they look just like an egg that you crack open to cook. These eggs were shipped to me. I have had "scrambled eggs" that I've cracked open to find the egg yolk busted. But these eggs are completely normal...just no signs of development.

These eggs were in an incubator with some Delaware eggs. I moved the Delaware eggs to a hatcher, where 3 of 4 hatched last Monday. So it's not the incubator settings. Please help me figure this out!

If the mother threw the egg out of the nest, maybe she had a good reason.

As for the egg left in the nest, there could be many reasons for that too. She might have gone to get a meal, planning to come back. Or she might have decided that egg was never going to hatch, so she abandoned it. Or maybe she decided the nest was not in a safe spot, so she made a new nest somewhere else and started laying new eggs there. Those are just a few samples of reasons the mother bird might be away from the nest, leaving an egg in it.


At this point, I would suggest putting it back, whether it is fertile or not, and then leave it alone. The mother bird can decide what to do with it.

Wild birds generally do better if people do not get involved.

Many places have laws against taking eggs or interfering with wild birds' nests, which is another good reason to leave them alone.

Ya something was prob wrong with the other 3 she threw out but matter in fact 1 time I saw 2 birds both female fly into the nest one flew off which look like the real mom and the one that was in the nest was to fat and short to be the mom I'm guessing she took over the test and threw the eggs out of it

Mkoh and no bird flew into that nest for a whole 6 days so for sure got left by the real and fake mom

Definitely a puzzling situation, but still best to leave them alone.

There are some kinds of birds that will lay eggs in other birds' nests, or may try to take over the nest built by someone else. Something like that may have been happening.

Mhm I'll see if no bird has got to the nest yet and prob take them out there tomorrow bc me and mo mom went to pick something up and we are driving for like 6 more hours but thanks for telling me this have a good day

Probably just not fertile. Did you notice any sort of bullseye on the yolk? That is a sign of fertility. No bullseye, no chickie.

Sorry about your eggs -

Then they weren't fertile to begin with..... what you have there is a "clear" egg. No fertilization. Dont feel bad, I just threw out 27 "clear" eggs.

Nope, no bullseye in any of the eggs. But the person I got them from doesn't think it possible that these eggs are infertile. I'm just trying to clarify what's wrong with the eggs, because I know it's not how they've been incubated or handled. But regardless, by day 7, IF the eggs are fertile, there absolutely should be veins and an embryo, correct?

On occasion, an egg will be missed on the "Fertility Conveyor Belt". It's either that or shipping damaged it enough so that development was stopped at the outset. And I even have another weird situation. After sending out my Lt. Brahma's eggs when she was in the pen with Suede to several people, they werent developing, even though I clearly had seen bullseyes in all I cracked open before that. The Buff Brahma's almost always developed, so I decided to incubate her eggs here just to see what was wrong. NONE would ever develop. I tried two different batches. Seems there is something genetically wrong with Miranda and her eggs, though fertile, just will not develop.

If she says they are fertile, could be something changed. My Delilah, who has been in with Suede for months, is no longer fertile. Could be all that fluff I trimmed has regrown or something is different about Suede's preferences now. Who knows? No more bullseyes, whereas previously, people have hatched her eggs. (doesn't matter, I'm taking her out of the breeding pen anyway)
