There is a difference but I take your point.
? Speaking of favourites, here's some tax. Dad up in the branches having fun with the kids, mum number two watching them from below because she can't fly (silkied bird problems), a random Tsouloufati hen that decided to photo bomb, and the star of the show checking out the nest
No I’m pretty sure he means this: the breeding duration is the time from the start of development of the embryo till the moment the chick hatches.
He means that the time for the embryo to develop is not always exact 21 days (or 20 days + … hours) and variations occur. An egg that cools down quickly after the egg is laid , will take longer to hatch when it goes into the incubator.
Good question!
Interesting statement!
Yes. I know of eggs under a broody who took 24 days with eggs in a nest/nestbox with a lid hanging outside a small coop. It was early spring and we had a lot of cold wind that month. The situation was discussed on a Dutch chicken forum. Some people said she should toss the eggs. If I recall right she got about 50% hatch rate with healthy chicks.
.. maybe some whiskeyMore a case of too many late nights due to social activities.
involved? I have been reading a lecture about hatching of different kind of birds, like kanaries, parrots and chickens as well. The differences are really interesting, it seems all bird species seem to know with how many eggs they should give a try to sit and wait.
Definitely comes from Henry. Dig is showing a relatively small problem but he's prone to it as well. Successfull treatment requires quite a lot of work. Luckily, both Mow and Dig are easy to catch and handle. See how it goes...
They will eat them eventually provided there is nothing better on offer; going foraging is something better as is just about anything I might bring apart from their grain mix.
that's a very interesting lecture report, and google translate makes a sufficiently good job of it that even the word-swap missteps are recoverable.. maybe some whiskey

The first part is about the day we don’t count when the embryo starts to develop inside the chicken.
The interesting part about different bird species translated with google:
Retention time
A pheasant lays about 15 to 20 eggs and only then begins to breed. A canary puts 4 to 5, sometimes one more. The Palawan peacock pheasant always lays only two and takes about four days. If you keep the eggs of the pheasant for ten days, you can say that none comes out. The eggs then seem to be unfertilized, but when it examined your germ disc, you would see that it was fertilized. You can easily store the eggs of a pheasant for about twenty days, without the outcome of the eggs leading to it. Nature does nothing for no reason.
As a rule of thumb, you can maintain that the number of days saved corresponds to the number of days it takes for a particular bird species to start breeding. So the pheasant three weeks and the Palawan peacock pheasant for four days.
You will come across everything with parrots. Most species lay an egg every once in the day. A Rosella can lay up to 12 eggs. Yet you can't keep the eggs of a Rosella for too long, that has to do with the fact that in nature that bird starts to hatch after the first or second egg. So here too you can see that the storage time has to do with the behavior of the breeding bird. With parrot-like, the rule of thumb is that you should keep the eggs as short as possible.
