➡ Quail Hatch Along🥚

I almost did that, but the instructions on the packaging said it would only be accurate if left attached to the plastic card... :confused:
I think it was in this thread where I read that? May have been in the Incubation & Hatching thread.

It is physically not possible for a bird's reproductive system to produce more than 1 ovum in a 24 to 26 hour time span.
Sometimes ( although fairly rare) two ovums will be released in quick succession, for whatever reasons. This usually results in a 'double yolker', if there is enough time in between the 2 ovum entering the shell pouch gland, then it would appear as though 2 eggs were layed in one day but it isn't physically possible for a hen to produce two ovums in a 24 to 26 hour period.
If it laid the first ovum in the shell pouch at 6 or 7am, then the second ovum at 5 or 6 pm, then it would appear as though 2 eggs where produced in one day.

When the first egg is laid, the follicle of the next ovum will rupture within a few minutes of that egg being laid, and thus taking 24 to 26 hours to go through the processes. Usually but not always, when the 2 egg a day myth arises the hen will skip the next 24 hours before producing another egg.
I had some melanistic pheasants that laid year round...not possible for seasonal breeders but it did happen, and sometimes I got 2 eggs a day, on occasion I got 3 eggs a day from this hen which I know isn't possible...'I thought'? So after researching this is what I found out about birds and egg production. Her reproductive system was really messed up. The second year of this hen laying this way resulted in 'shell less' eggs and finally EYP and eventually she stopped producing any eggs....laying for less than 2 years.

:goodpost:

I have four hens that frequently lay two or three eggs in a 24 hr period, I was wondering about the science behind it. One did it yesterday so now I'm going to pay attention to if she skips today (she also hadn't laid in ~2 days before). Poor little backed up things xD

It usually is noticed more with heavy layers and battery hens.
 
Only home-hatched coturnix here :confused: A few of mine do lay like mad. I have noticed they do tend to either be regular once a day every day or more irregular and potentially more eggs .
I haven't seen this problem with my quail, even when raising them commercially.
Pheasants seem more prone to this happening. Currently (last year)I have a Yellow Golden hen that's been doing this, half way through last season she quit laying too, hasn't layed an egg so far this season.
