Yesterday, the hen pushed one of the eggs out of the nest. It was found at the bottom of the bird cage and slightly broken. I had no choice but to carefully take the broken egg apart, and I found a lifeless chick inside. I didn't know for sure if the chick was dead, so I placed it back into the nest. This morning I found the same chick at the bottom of the cage again. It must be pushed out by the hen again. It was still lifeless as before. Poor little thing. No idea what really had happened, maybe somehow the chick died before it could hatch and the hen sensed it and pushed the egg out.
However, since yesterday afternoon the hen has been acting unusual. She spent a lot of time outside the nest, and when she is inside the nest she doesn't really sit on the eggs any more. I am afraid the eggs might die if they are not kept warm. On the other hand, it has been 23~24 days since the hen had been sitting on the eggs. I thought the eggs should have hatched if nothing had gone wrong.
