On the flip side our top hen, big mama (BLRW) is setting now and we do not plan to move her. She's left the best for 30 mins at a time and no one else dare touch the nest! Our Roo, Luna, bantam EE, even went in and watched the nest till she went back in... it was the cutest thing ever.
We have a top hen, "Princess Lay-a," who likes to go broody once a year. When she does, her chicks are the most entitled balls of fluff you've ever seen. If one of her chicks walks up to a food dish, the adult hens will back away because they know their mama's coming. I even saw Princess walk off away from her chicks & then a roo made a warning call. The nearest hen quickly covered 2 of the chicks on instinct.
The last batch she hatched slept on the high roost between Princess & the Roo. She never truly abandoned them & they still sleep up there at 10 months old. (We call them our "Millennials." LOL)
