This weekend was a "work on the run" weekend. My son and I were working on the run where our TSC pullets are going to range when I heard the chicken song come from the pen where we have our Sebrights and Leghorns. My son thought it was one of the girls who are now 16 weeks old but I was sure that it came from the Sebright pen. There was no egg but it was great hearing the song for once.
