One of my Buff Orpingtons layed her first egg yesterday. I didn't know who had laid it, until I caught her on the nest today. She gave me another pretty little brown egg, so I gave her a small tomatoe, and a few laying pellets as a reward. I bought this little hen as a chick, in April , so she is 4 1/2 months old. The odd thing is I found the first egg, still warm at 11:30am when I let the chickens out for the day, and todays egg came at 6:00pm.
