This worked perfect on my white duck eggs. I could see development progressing, but no fine detail. In the instructions it says for light coloured eggs only, which is something I wished I had known before I purchased this one. I think I would have bought the upgraded one.
Great little candler, suitable for school or small poultry breeders. Easy to use with very clear instructions and diagrams about egg development and what to look for.
Easy to use with excellent results.. The kids think it is wonderful as the contents are so easily visable.. a very useful aid to home incubating...Sarah.
Facinating being able to watch things develop even before they hatch and this neat little gadget makes it all so simple.
