yes that is the safest thing to do!
The Cowbird never has its own nest - it uses the finch nest as its host (read: parasite.) The Cowbird egg will hatch first & will push the other eggs or baby finches out of the nest. Other species of birds will get rid of the Cowbird eggs, but finches don't seem to. I always remove them when found.
As long as they have a fertile rooster around who is breeding with them, they should certainly lay fertile eggs, though golden sex links only very rarely get broody and sit on eggs themselves.
This is very easy simply make scrambled eggs like the rest of you American cannibals or become a vegetarian and stuff them down your nose.
A finch? Unless I'm thinking of the wrong animal, it's a bird and it can lay fertile eggs that can be hatched. but you must have a male finch with the female, otherwise any eggs it lays will be infertile.
Do you have a Rooster living with Hens? If so, chances are, yes, the eggs will be fertile. If the hen is brooding, meaning she is sitting on top of the egg to keep it warm, then it's probably fertile, if not, then it's not fertile. In any case should you have a rooster and a hen together, and the hen lays an egg, and it doesn't brood, then you should keep the egg warm. I think to check just hold the egg up to a light lol.
some are. There are soooooooo many types of finch, some of their eggs are blue, some are white with brown spots.
No, pufferfish will not lay non-fertile eggs. I have had multiple pufferfish for over 5 years and they haven't laid non-fertile eggs. Although she did mate with my other pufferfish and lay fertile eggs.
YES!!!!!!!!!!!!
Parrot eggs are either fertile when they are laid or they are not fertile when they are laid. They have to be fertile and properly incubated in order to hatch.
These eggs may not be fertile. Leave them there and see what happens or maybe take them to a vet to be inspected.
Finch eggs hatch about 14 days from the last layed egg. They hatch in the order that they are laied
