Oh well... tons of news over here. My broody is about a week away from hatch day and since she's been there I've only been getting 1-3 eggs per day that the other hens lay on top of her. I thought maybe they were too scared of Mrs. Broody to want to go in there and lay. I was right and wrong.
My kids left the feed pellet box open. They've been laying in there, right on top of the feed. The sight of all those eggs made my barred rock decide to brood, also. She's aggressively guarding 15-20 eggs while sitting on the entire stock of feed. She's my alpha hen, too. Who knows where the other hens are going to lay now.
I'm considering moving Mrs. Alpha hen into the chickpen with Mrs. Broody tonight after dark. I was going to do a day 14 candle of Mrs. Broodys eggs anyway. With two weeks between their hatch days, does anyone think it would be a problem to make them share a brooding pen? Will Mrs. Alpha abandon her eggs when Mrs. Broodys eggs hatch? If I have to I can probably move Mrs. Alpha elsewhere. Opinions?
That might not be the best of ideas. Mrs. Alpha may decide the chicks that hatch under Mrs. Broody are now her chicks and she might abandon the developing eggs. Or she could turn aggressive and kill the chicks that aren't under her. Another thing you will have to contend with is egg stealing. My "Queen of the Coop" and her "Second in command" went broody within a couple days of each other. Queeny took #2's eggs and made her brood in an empty nest. If that happens in your situation you will have a bunch of mixed up eggs.
It would be best to give Mrs. Alpha her own broody pen until after the chicks have hatched and she has had ample time to bond with them. Once bonded combining them shouldn't be an issue. Mrs. Alpha will be an active protector of her chicks, so the older chicks won't bother them.
