My girls are now 21 weeks. At 16 weeks one of them laid a huge, oddly shaped egg, outside the coop on the ground. Today, 5 weeks later, I found a tiny egg the size of a jelly bean in the nest box. It was so funny looking next to the big huge honker of an egg. Why would she drop a huge egg in the run and 5 weeks later drop a jelly bean in the nest box? Could this be 2 different birds? With all these shenanigans, I don't know what to expect or who is laying these random eggs. It is like an Easter egg hunt every day with my girls. Any thoughts?
