Well yeah but you have to have them arrive the day your hen goes broody and hope they will hatch before she gives up and leaves the nest
For better or worse, mostly worse since I don't often need more chickens, none of my hens that have gone broody ever willingly leave a nest. I decided to get 7 chicks this May after 4 of my hens were on "broody trip" number two this year and the 9 hens are 3 years old so they are slowing down and the Cubalaya "Yard Art" were never much in the way of laying - expected for the breed though.
I had broken the other 3 but decided to let my
big Black Australorp stay broody when I found I could get the kind of chicks I wanted (*) pretty quick from Meyer Hatchery. Zorra laid from 3/5 to 4/18 then broody. Laid from 5/5 to 5/27 then broody. The chicks came 6/10 and were put under her at 0
REALLY dark thirty on the 11th after my getting nervous when we tried at 0
fairly dark thirty on the 10th. In the meantime one of the Faverolles and one of the Cubalayas went broody AGAIN around the 2nd so I let them stay broody just in case Zorra didn't take the chicks. She did and I stuffed the other girls in the buster.
Then the OTHER Faverolles went broody on the 12th - straight into the buster. Mind you this is the THRID time for these 3 girls this spring! She broke and let her out. Zorra chased her away from the chicks for a couple of weeks but somehow she has become the "aunt" and the little family of 9 (chicks now 7 weeks old) are being mothered 24x7 by two hens.
Mind you the Anconas have NO interest in the chicks and while they were clearly top of the pecking order and routinely let everyone know it just in case they forgot (though I think purely due to her 1.5X their size factor they never bothered Zorra much) they have been cowed by Zorra's "hen from hell" protectiveness of the chicks. They can't even walk past without being chased out. And now one of them is in serious moult so she is nervous in her "unprotected" state anyway.
* though I'm pretty convinced the "Black Australorps" I got are Jersey Giants given their VERY yellow feet. Not a breed I wanted at all. We don't eat the chickens so their "roasting size" will be nothing but a food burner disadvantage in the winter when they can't forage and they aren't likely to lay anywhere near as well as BAs do - in general. Zorra isn't a great layer but her "sister" is my BEST layer, closely followed by an EE.
