I have a Buff orpington who has been laying for a fews weeks now,i've watched her lay so i know the non speckled light brown are hers. I also have a white leghorn who has just started laying in the last few days. I know its her because the new eggs are white. I also have a black Australorp and Rhode Island red. i just got a light brown egg with darker speckles on it. so im not sure if its the RR or Australorp egg or if it's the orpingtons. Can the orpingtons have speckled eggs or is it more likely one of the other birds egg? i'll try to post pics...thanks!
