no you can not touch an duck egg and the mom will come back because the mom will get jealous and kill there babies so dont touch a duck egg
you touch it
Just wait for it to hatch, "touch" the egg a bit.
all you have to do is keep it there and not to touch it.
You shouldn't move them because it could ruin their growth and don't touch them or the egg could break...so just don't touch the egg. If you did touch an egg in a bird's nest, you probably did no harm, but you must stay away from them. Human curiosity and small, delicate bird's eggs in the wild don't mix very well.
Touch overweight egg sauces
When an egg is placed in Kary syrup the egg releases the water inside of it to achieve diffusion. There is a higher concentration of water in the egg than in the Karo syrup. When you touch the egg after it was left in the Karo syrup overnight you will find that it collapses under your touch because it has lost some of its volume (the water). The egg will also shrink in size.
Yes Penguins will bite you if you try to touch them or their EGG
Nothing harmful, maybe it will bite you or something but it won't abandon the egg
NO definitely not if you were to touch the eggs no matter how old it is, the parents would kill and eat the baby. The reason for this is, once you touch an egg and the parents are still around you leave your human scent on the egg which will then mix the scents of the baby and you. Once that happens the parent cant tell if the egg is theres or not so they kill it,which means you should just let the parents do all the touching.
the mother bird will not come back to the nest, and will just leave the egg there.
if its fertile ans incubated yes
