She hatched her 3 eggs. Is thier anything I can do to encourage her from comming out of her broody stage. Or since she has hatched these 3 that were not her own eggs. How long before she starts to lay her own again. I have no rooster. The eggs that hatched were from a friend who had a rooster. Could she be aware that the new chickes were not hers?She acts likee a good mother How long dose a chicken stay broody?
You've got a lot of different questions there... and some missing information so I'll have to make some assumptions (ie how long ago did she hatch these chicks; you said new so I'll presume a day or two old, and I presume these chicks are still with the hen).
First, a broody hen will sit on any eggs and hatch whatever is beneath her. She doesn't care (other than they be bird types I suppose...although I've read funny stories on that too). She will mother the chicks she hatches. She does not care they are not her eggs.
Secondly, how long she mothers depends on the hen.
Good mothers stay with the chicks until the chicks are fully feathered and can fend for themselves...usually the "golden" age for that is 6 to 8 weeks depending upon breed and conditions. I like to see the chicks at least 6 or 7 weeks old, preferably 8 weeks, before they integrate into the flock with the mother hen who protects them from the flock as they integrate. At any point thereafter, she can begin to distance herself and lay again.
Some hens barely stay with the new chicks and are on to laying and nesting again. Those are actually poor mothers as the baby chicks are not ready to be without a mother. .
My Welsummer mothered until 7 weeks. It was warmer weather and the chicks were fully feather. She had taught them to scratch, find food, find water, and that last week she had taught them to perch. She then showed she was thoroughly done (pacing beside the fence to be let into the main flock). She had also begun the little "egg dance" that 7th week and within the week was laying again.
My Silkie is still with her hatchlings which are now 8 weeks. She stayed with the last hatch until they were about 12 weeks, and began laying within a couple weeks of that. Silkies are simply more long suffering mothers brooding longer than is really necessary.
How long for a broody hen who has hatched and mothered to lay? Again depends upon the hen...how long she mothers, how long it take her to finish molting. Hens molt after brooding. (Providential nature's way of cleaning her up after sitting on eggs for so long and having chicks crawl through her feathers poo-ing.)
Like I said, my Welsummer finished with the chicks on week 7 and was laying by week 8. I've yet to see my Silkie in the mood to lay. Different hens. Different birds.
You could possibly hurry the process up by taking the chicks away....or you could just prolong her broody behavior as she will be distressed she lost her chicks so early and want to begin all over again. (That happened with my Black Star.)
I personally wouldn't break her from brooding and caring for her brood if you ever plan to use her again to hatch and brood chicks. Her staying with them and caring for them is a sign of a good mother, and your life is free, free, free from heat lamps and incubators. Letting her finish the process out will allow her to be a good mother and not prolong her broody instincts.
My 2 cents from my experiences.
