We have 5 hens, no roosters. All are approx 1&1/2 years old. they have been healthy, laying great eggs on a regular basis. Recently we noticed one of our hens (a Brahma), has what looks like a forming embryo in some of her eggs, with tiny pieces of brown matter...anyone know if this is a problem? Another behavior that has recently started is our Black Star is acting like a rooster sometimes, if you get my drift! Just curious, any info is appreciated.
