Gouldian egg weights

[Blue Cuban]

Is there any information on the progression of development in a Gouldian egg regarding its weight.

Curious to know what is considered a heavy egg and what gains are to be expected by the hatching date.

That's out of my league mate,i just wait till they hatch and colour then CULL Craig

Haha....
I know breeders over seas do just interested to see how deep Australian's have looked at there own birds plus I have a bird producing some visually big eggs and I was wondering how these would compare to others.

I suppose if your looking at keeping jumbo sized Gouldians just keep the bigger eggs....I do what Craig does...pick the best and flick the rest...

Small Eggs, small Chicks, big Eggs big Chicks,
I am not a scientific Person, I breed for the sheer enjoyment of it
as Craig said, they will hatch in due time, if the Eggs have been filled,
let them grow and colour up and then decide what you want to keep and what you dont want to keep.
I recognize the importance to find out what makes our birds tick and how to arrest the decline
of a certain spieci but,the weight of an egg at a certain stage of incubation?
what is the reason for that of that? sounds like another round of continental Hog Wash
when I read this kind of unholy bolony it ruffles my head feathers to no end, with my tail feathers already on the war path.

Interesting question, and absolutely no harm in a bit of quantitative research.

I have no recollection of reading anything about this, but Sarah Pryke's research involved numerous measurements of different parameters of Gouldian finches

Don't think egg size would have much bearing on the mature size of Gouldian, from either small or large eggs. Regards

I just leave my breeding birds alone, there is enough pressure on the parents trying to be successful breeders without
me fiddling with nests and contents. Let the scientists do that as their breeding stock is raised to put up with constant
human contact.

I agree with not interfering too, but am convinced a bigger egg results in a significant body size advantage from day one.
