And do you have any tips for stimulating a chicken to go broody? I"ve read about putting golf balls, or ping pong balls... Maybe a dark carrier with a blanket over it? And Cochins or game hens being broodiest.... And how many chicks per hen on average? What is a clutch size?
Too many questinos...
Some report leaving golf balls or fake eggs in the nest at a certain time of year can trigger a broody...I've tried leaving eggs in the nest for up to 10 days around the time my broody would normally go but it didn't work. Mostly I find they will go broody when their individual hormones signal for it and not until.
I've heard of Cochin, game hens, bantams and Silkies being extra broody...I've had none of those breeds so cannot testify to that being a consistent behavior of these breeds. Certainly there are breeds that are more likely to yield a broody and the Cochin is well known for it and is also large enough to cover quite a clutch of eggs.
The hen will usually choose a clutch size when on her own in a secret nest and that can vary. Most people will use up to 10-12 eggs for large fowl birds and 6-8 eggs for bantam or small breeds.
If introducing foster chicks to a broody it all depends on the size of the bird how many chicks one can stuff under her. I've placed 20 Cornish Cross meat chicks under a White Rock broody before and she covered and raised them all successfully. I know a lady right now that is using a Silkie for the same purpose and I think she placed 15 meat breed chicks under that hen and she is doing well right now in keeping them warm and safe.
