Simply pick them up, and shoo them out of/ away from the nest/nesting boxes. Repeat this as many times as neccessary, they should catch on eventually!
When hens are broody they are not 'themselves'. Try taking her off the nest and putting her in a cage, somewhere she is isolated from the other hens and also where there is no nesting box. That always works well for my hens.
It really depends on how good a broody the hen is, and the reliability of your incubator and your experience incubating chicks.
They either have a parasite or they have been fighting.
I have Silkie Chickens who are very broody, they are little bantam chickens that look like little cotton balls.
No. A broody hen is a broody hen and will sit on golf balls once the urge to nest takes her. Hens do not instinctively know if the eggs they are brooding are fertile or not. Hens in a chicken coop without a rooster among the flock will still go broody.
Brood means to worry. It originally referred to the behaviour of hens sitting on hens to make them hatch. The behaviour of the hens at this time became "broody"--worried.
Some hens just aren't built for being broody. Although, if there is continuous disturbance, (ie. noise from the house, other hens trying to lay etc), then this would cause her to leave her clutch.
Broody hens do lay eggs. They actually lay one [1] egg every day or two.
Because it is a natural instinct for them to go broody
In my experience using Silkie Broody Hens, you do often get two sharing the brooding, and happily share the parenting. I've never had these hens kill chicks, quite the opposite, they are both very protective of them . Of course if you have a new batch of eggs you want to hatch move one broody hen on to them and she will sit. Hope this helps
No. The rooster makes the hen's eggs fertile. From your question, it sounds like you want a hen to hatch some eggs. If so, some breeds or crosses are far more likely to go broody than others. Also, particularly if the chickens are in a pen/run rather than free ranging, a rooster will discourage broodiness rather than encourage it. A rooster also reduces egg production - in both cases its because he chases the hens a little to control them and mate with them, so egg production drops.
If you are asking how to make the hens go broody, then there is no surefire way. To encourage broody-ness, you should put fake eggs in her favourite laying box.
