We found the first egg from some new hens last night!! Problem is...it had been cracked and eaten. In the pen are 2 silkie roosters, 1 silkie hen and 1 white langshan hen...all sweethearts and get along famously. The egg was from the langshan hen as it was light brown. We've been checking the pens 3-4 times/day and she had to have laid this egg between 4:30 pm and 9:00 pm last night...that's when we found it. So who's the culprit and how do I prevent it?
