We have had a number of people post that they saw a third egg laid last night around 6-6:30pm (nest time). I was watching during part of that time and it certainly looked like she was laying an egg. Unfortunately we do not have a great view this year into the bottom of the nest. We will all continue to watch as they incubate the eggs for the next few weeks. If we are lucky we may get a better look sometime as they roll the eggs. If not, we will have to wait and see how many hatch next month. That may be the ultimate answer to the question...2 or 3?
