Two weeks ago our BAs started singing their egg songs, but we still don't have any eggs. This morning just before 11, one of them launched into the longest egg song yet. I went outside after she had been done for about five or so minutes, still no egg. While I was out there, she started making this weird yipping sound. Is this normal?!?! The second time she did it (the time I recorded) she shook her head on the first yip. She's about 27 weeks old now, no signs of a health problem... walking perfectly normal, no mites or fleas, etc. Link to audio (it should just play in your browser) http://www.ourmisadventures.com/wp-content/uploads/2011/10/selma_yipping.m4a The clucking and honking are from her sisters, the only sounds she made were the yips.
