I think it’s definitely coming. I haven’t seen her out of the box today. It’s bedtime and shes not heading to the roost like usual. I feel bad trying to break her
Check for the other signs I posted.
She'll be fine being broken, the sooner you catch it the better and easier it will be...but...
You'll need to decide if you
want her to hatch out some chicks, and how you will 'manage' it.
Do you have, or can you get, some fertile eggs?
Do you have the space needed? Both for more chickens and she may need to be separated by wire from the rest of the flock.
Do you have a plan on what to do with the inevitable males? Rehome, butcher, keep in separate 'bachelor pad'?
When I have a broody and want her to hatch I wait until she's been in the nest most the day
and all night for 2-3 days...along with those other signs I posted.
Then I put her in the broody enclosure with fake eggs in the floor nest, she won't like being moved, but if she is
truly good and broody she will settle onto the new nest within a half a day.
Then I give her fresh fertile eggs and mark the calendar.
I like them separated by wire from the flock, it's just easier all around.
No having to mark eggs and remove any additions daily, no taking up a laying nest, no going back to the wrong nest after the daily constitutional.
I remove barrier about one week after hatch. The chicks are usually safe it's the broody who has to 'fight' her way back into the pecking order...which can be quick or take a few days.
Lots of space helps for re-integration.
If you let her hatch, no matter how you set it up,
this is a great thread for reference and to ask questions:
It's a long one but just start reading the first few pages, then browse thru some more at random.
