Hatching Tribbles

Incubating Tribble eggs poses unsolved problems.

I put a probe under a hen with eggs & it reads 100.5 degrees, so they may want more heat?
Humidity may also be part of our problem?

I brought 2 hens inside one January 1st & ran a small space heater. Despite hanging a thick, wet towel, which went bone dry every 12 hours,
every bit of moisture was sucked out of the room, the hens & the eggs. Both hens still hatched a clutch.

Here are suggestions I have gotten from others:

Michael in New Jersey shared some of his thoughts about why Tribbles might be suffocating or drowning before they can hatch:
So, the way seramas are described across the internet gives me the assumption that they are as difficult to hatch/raise as the
closely related species in the Coturnix genus via incubator.

Both a typical serama (~300-480g) and serama egg (~18-24g) are much closer to the domesticated quail/coturnix (150-300g)
and its egg (10g) in size/weight compared to an average chicken (~2400g-6240g) and egg (~50-70g). Even the number of days for
incubation appears to match; 17-20 for Coturnix, and 18-21 for seramas, compared to ~21 for full sized chickens
and their wild counterparts in the Gallus genus. Shorter incubation time could be caused by physiological changes due to
the significant miniaturization of seramas as it exists in similarly sized quail.

In theory, best hatch rates may be possible by mimicking the environment of a quail egg rather than chicken egg.
Differences would include lower incubation and hatching humidity by about 10-15% less for both in order to dry out an incubating
chick so that the small egg’s air cell expands large enough to allow the developing chick to breathe, lockdown time for eggs
started on day 14-15 rather than 18, which gives a nearly fully developed chick more time to position itself into hatching
and a lower hatching temperature of about ~37.2*C. Lower humidity needs can be supported by the fact that regular
sized chickens are known to suffocate in the egg due to poor development of the air cell in high humidity.
Lower temperature may be required as a faster developing smaller chick develops thermoregulation earlier and begins to produce
its own minute amount of warmth. In general it is logical that a smaller chick requires lower
range humidity/temperature throughout its egg stage of development due naturally higher fragility
at higher range values of both compared to the lows. Theoretically, diet should also be changed. Coturnix species are
generally smaller than Gallus species and also happen to have
shorter lifespans by several years.
This is partially attributed to a faster metabolism (associated
with faster development and shorter life) required to heat a smaller sized warm blooded organism since it loses heat faster
due to a larger surface area to volume ratio. Quails are given a higher protein diet (22-30% protein, a game bird diet) compared
to regular chickens in order to match growth rates and for thermoregulation. A regular chicken diet (~14-22%

protein) given to a quail and serama could in theory potentially cause failure to thrive growth, slower and/or stunted growth,
as is the case for meat chicken breeds/fryers fed a regular chicken diet (they normally require a diet 20-24% protein to
grow at their optimum rate). This is also supported by the understanding
that the fast growth in earlier stages of life in the two genus require protein percentages in the higher range compared to the
lower range percentage of their respective adult diets. Again, this is all theory generally based on seramas size being
closer to Coturnix compared to all species in Gallus.
All this would require some experimenting/study in order to confirm or debunk these ideas.

Fresh eggs are collected & stored in climate control
Shipment may include eggs from my smooth-feathered breeders.
These birds hatch 50/50 smooth & silkied.
Breeding them back into my flock increases feather strength.

Eggs are marked. Here is the code

Eggs are very well packed for shipping.
