Our broody hen had almost got her chicks to hatch one had a massive hole and she kicked it out of the nest I was able to get a quick photo but when I tried putting it back under her she pecked at it and there was blood!!!! What should I do about it.
Remove all the eggs immediately. She'll kill the whole hatch. Place the eggs in an incubator. If no incubator, incubate them yourself. (If you have to do that, candle the eggs in a dark room so you're not incubating duds. )
