I've never lost a chick before, but this week I have had two mysterious deaths. My chicks are secure and have fresh food and water. Of the nine chicks, I believe that four of them were males. Two of the four have died. When I went for my therapeutic chick watching I observed my silver sebright chick pestering my golden sebright chick to no end...the two of them I believe to be males. Could my chick be guilty of stressing/bullying my other two chicks to death? They are about four, maybe five weeks of age.
