Hi everyone, this morning when my mum went out to let the chickens out of their coop, she found an egg after one of the chickens was making a strange noise. The egg was very strange as is seen below: Uploaded with http://imageshack.us As you can see clearly, the bottom has been eaten out, and the yolk, drained. We are not sure if she has laid a mutant egg or if this is a predator. We are also considering that this may just be a malformed egg (this has never happened before). Our chicken seemed lethargic and she wasn't eating, she also seemed kind of pale. The egg is at least one day old (since my mum found water in it from the rain yesterday) and the shell is abnormally soft, It also has a slight discoloration at the bottom, it seems more pale than an egg usually is. Could it be a predator or a health issue? Any ideas?
