I have a weird chicken. When my hen Willie laid her first egg I was happy because all the other eggs were brown, which I love, but Willie laid white ones and that was a nice contrast they were really so white. Then suddenly no white eggs, I thought something was wrong with her, but I was getting a brown egg for each hen almost every day. Well over the few years I have her I found with certainly that Willie lays white eggs then she lays brown eggs. This changed a few times in her life. This last week she was laying brown and then all of a sudden they are white. I am down to three hens so there is no mixing this up. Has anyone ever heard or this? this is not my imagination I am absolutely positive this happens but want to know if we are the only ones.
