Eggs Candling Development Stages, Aviary Birds in the Bird Gallery

Sharing buttons:


hi guys a new update from the bird

gallery this breeding season is not

going great

missing eggs egg eaters and egg binding

we've seen it all today I will show you

how I check the only two nests left

those of the purple press is called

instinct and the eggs starfish

checking your eggs or as we call it

Kendall your ex is one of the most

exciting parts of the breeding season

for those people who don't know what

Kendall in your ex's I will explain

briefly put simply candling is the name

given to looking at the inside of a

developing end by shining a bright light

fruits we do this to check whether an

egg is fertile and to check at different

stages during the incubation to see

whether the embryo is developing

correctly so to do this we use a very

strong flashlight the brighter the

better and perform it in a dark blue

always be very careful but work quickly

the cold can affect our development I

will do it by hand but to be extra safe

you can use a holder which can consist

of a small board with a hole in it just

a little smaller than the end even a

phone will work as a light just put the

flashlight under the act so you can

shine through it

eggs are normally handled after five to

six days of incubation the most critical

period during the development of embryos

is the first week so it's best to be

patients and only take a look after the

fifth day all the eggs near the top

between your thumb and forefinger till

the egg slightly to one side rotate

until you get the best view a day one

the egg is almost white it's some

yellowish dough at the five incubation

you can just begin to see the tiny dot

of the embryo in the middle with veins

running off to the sides at the eighth

you can already feel smaller at day ten

it's getting darker and darker and

embryo is filling up more space

at day 14 the air sac is getting bigger

and you only see a dark figure

however it's not wise to send all the

eggs at this stage because you can

harvest it inside the chick will hatch

very soon if you have an unfertilized

egg you only see a yellow spot after

five days incubation the rest is why if

the whole egg is yellowed the embryo

died from very early develop and if half

the egg is dark and the other half is

white the embryo died in late celibacy

now it's time to check our eggs first

let's start with a golden finches


unfortunately we see that they are all

and fertilized this is already the

second nest with unfertilized man so I

have to look where the problem could be

now let's check the starving

with more luck here one hang in late

development all the rest unfortunately

died in different stages and indeed

after a couple of days we found a little

chick in earnest

and these birds lay very tiny acts we

check out this egg


else have some sad news the white

breasted golden finch did not make it

and died a couple of days after I posted

the video I don't exactly know what the

problem was that the bill looks fine so

I hope it was not a transmittable

disease hopefully we can quickly find a

new partner for this handsome boy so we

can still have nest this year well that

was it for now hope you enjoyed this

video if so hit that like button and

with our most beautiful golden finish

thanks for watching and remember stay
