I have 32 eggs in one bater and 24 in the other, the one with the 32 has shipped silkies, only 2 out of all of them did not look fertilized I have 11, so 9 or less will make it, all mine that I got from my flock were fertilized, im candling tonight the one that has the 24, there from my sisters chickens and a friends of hers, were swaping baby's once hatched, I have been having issues with the temperature on that one, so im hoping they make it anyway, its a cheaper bate, the one with my silkies is my better bator.
