Surely if a egg is in a incubator (or under a hen for that matter) and it have red veins and growth in the egg then it is hatchable otherwise it would not develop?

So why would fertile eggs not hatch even if you can see the veins and growth inside? Would this just be down to the hen or incubator not doing a good job or does the nutrition of the parent bird, season, damage during travel, incorrect storage of eggs, problems with incubation, fatal genes etc still come into play?


Because the factors that can affect hatchability continue to do so until the chick has hatched and is free of the egg. :D

If you can see the veins in a developing egg this only means you have proof of fertility without having to break the egg open.

If for instance the parent birds' nutrition was poor the chick may not be strong enough to pip through the egg shell.

If the humidity was too high the chick may drown inside the egg.

These are only two examples for what can go wrong AFTER the embryo has started to develop.

We are doing muscovys at the moment. got an incubator full of eggs and have more we will have to sell or eat. It also looks like the khakis are starting to lay as well. Eggciting!!! sorry for the pun.

The Appleyards and Pekin breeds on our place only had a childrens' paddling pool each to swim around in. They were quite happy with that.

Now that the Appeyards are able to free range (no cross-fertilisation between the breeds - drake really don't care what breed they mate with), the Appleyards wander around the area of their paddock and one paddock either side. They don't actually travel far and they don't fly, preferring to walk everywhere. So you won't have trouble with them roaming off somewhere - once they've established themselves at your place, that is.

45 hectares between Whangarei and Paparoa. Registered Dexter cattle, Wiltshire sheep - black, white & pied.
New Hampshire Red poultry & Dorking poultry. Pilgrim Geese, Appleyard Ducks.
A cat called Pusscat and still looking for another heading dog.

Ducking Around, if you are so fond of ducks, would you like to consider Magpie Ducks? They are now a very rare breed and need more people breeding them. If you email me, I can email you the contact details of a guy who breeds them.
