This morning my husband went to check on the chickens and all 12 were going about their normal business. This afternoon, he found one of my white chickens (amber link - about 10 mos old) dead in the laying bay, no egg but bloody bottom. Was she egg bound???? Was she sick? Any info would be greatly appreciated. This is our first group of gals and we love them dearly and don't want to see anymore leave us.
