Chickens can and do lay a wide variety of eggs in a natural environment. Colour variations from the same chook, funky shapes and textures/bumps are all things that you don’t see in supermarket eggs as they are removed from the commercial market. But some eggs can truely make you scratch your head in wonder and even cause concern, wondering if there is something wrong with your girl. This great resource from Alltech can help determine the cause of your egg abnormalities and whether it is a blip in their reproductive systems (and therefore nothing to worry about ’cause nature is nature) or whether it is something more sinister and a change of diet or supplement is needed.
Either way, hopefully the answer to your egg quality issues can be found here.
