I'm of the camp that the hen will do what she needs to do when she needs to do it, so I don't mess with my broodies unless there is a compelling reason to.I have a buff orpington that went missing. I found her hiding beneath a bush, up against our house with 11 eggs. She is quite far from the chicken coop on the side of our house that the chickens rarely wander to because it is just gravel and driveway. I put some water and food where she can reach it, but I don't think she has moved off her eggs once. I have read that she should be getting up to stretch her legs. I think she has been there for at least 10 days. Should I try to get her up to walk? She is not happy to see me when I stop by to visit. As soon as I put my hand in to move the bushes back she starts to screech.
She is getting up, you are just not there to see it (unless you stand over her 24/7). They stretch, drink/eat, and poo about once a day (sometimes every other day) for about 15 minutes, then go back to the nest. Remember she is incubating and keeping a consistent temperature and humidity for those eggs. If you had them in an incubator, you'd be worried if you turned the incubator off for 30 minutes or longer so you could stretch.
If she is safe where she is, she'll get the food and water when she wants to...and in another 11 days, she'll have a little clutch for you to oogle.
