I have a hen who has been brooding about 10 days now. I have followed the advice I have read on this blog but nothing has worked. I dunked her in icy water twice in one day, once in the morning and once in the evening. She got as mad as a wet hen both times but went right back to sitting on eggs. I have removed the eggs that are there daily. She then just moves off the nest and goes to another one with eggs. I've run out of tactics. How do I normalize this hen?
