I just went outside and found my favorite BO laying dead in the middle of the coop. No signs of trauma or anything. She looks like she just laid down and died. Aprox. age was 8 1/2 months. She was my rowdy girl, last one up the ramp when I needed to lock them up and protesting all the way up! Could changing their feed have anything to do with it? Don't ask me why, but as a 'change' I switched from layer feed to regular scratch. Even made the comment that if they didn't like it or had problems with it, I would go right back. Could that have anything to do with it? Whether or not it did, I'm going to always have that in the back of my mind. R.I.P. Ruth, first rate Chickie Girl.
