Young girls can be and often are slow in the box to lay. I've seen them go in sit an hour, come out without laying an egg and do it several times till their body gets it right and they lay an egg. Give them a couple months to get with the program and they will be in and out after laying in no time.Pre broody behavior... I always see outside among the flock starting a couple days in advance... indicated by the head dropping down and wings flaring out plus a bit of a cluck cluck sound.
The other behaviors I have seen as a standard pecking order, I'm laying here, leave me alone type thing.
I also will NOT let pullets sit, hatch, or brood chicks... until 1 year old as her mind AND body are still going through changes.
In my experience... even truly broody hens can continue laying up to 3 days AFTER they start sitting. But being slow in the box is pretty normal for some ladies.![]()
