nah.. I remove eggs all the time for candling/weighing/air cell checking.. and I do more than 6 at a time...
the only time you REALLY need to worry about those few minutes of cooling is with teeny tiny eggs.. like quail and some of the parrot eggs.. bantam sized birds would be the next in size...
they could be laid late then... have you seen much movement in the egg (just under the membrane or showing as moving lump/bump in the air cell)?... if you're seeing movement in the air cell.. but not an internal pip.. it would indicate an egg closer to hatch
Muscovy do have a tendency to have a fair amount of "glop" in the bottom of the egg.. a bit more than what would be usual for a regular duck... most will hatch just fine with it... it's thicker and tends to stay in the pointy end of the egg.. you will find it in flamingo eggs too.. and when you...
As I predicted.. our broody muscovy had her nest raided last night. I'm betting on raccoons.. they left behind one egg (which I found this afternoon).. it was pretty cold, but I did candle and see the lil spider .. couldn't tell if the heart was still beating or not.. so I plopped it into one of...
eggs up to a month old CAN hatch IF they were stored properly... I've done it myself with a method I came up with for storing my excess hatching eggs.. however if they were just sitting on the counter I would candle the older ones to check the air cell size and toss any who have big air cells...
if they are being incubated consistently... you should begin to see veins on the VERY early ones around 4 days... I never count any muscovy egg out though until day 10 just to be sure since they have a longer incubation.. if you have them under a broody who is constantly getting up.. or if the...
it depends... was it caused by someone assisting too early?.. or was it ruptured when the duckling hatched on it's own?
If by assist.. well.. they went in too early.. plain and simple
but usually it's caused by a bacterial infection (omphalitis) or improper turning of the egg during the...
