I was delighted to see a couple weeks ago that my best brooder was ready to set. (Four year old black silky). I have been wanting to raise some black jersey giants and had gotten fertile eggs from a friend. Everything was great with my hen and her three eggs for about two weeks. Then without warning she abandoned the nest and the jersey eggs were lost, so not like her! But I figured "it happens" and would try again in the summer. Well two days ago my little silky girl was found dead on her nest. So now my best girl is gone for no apparent reason. She was eating and was not egg bound. She seemed fine. What could have happened? Any ideas?
