You are not alone!
My RIR hen, a little over two years old, is broody for the first time. This has been going on for three weeks. There are no eggs under her, and I have no rooster, so no way to get fertilized eggs. I am not set up for baby chicks right now, so have been lifting her out of the nest box twice a day and placing her gently on the ground. She is all puffed up and confused for a moment, then shakes herself and runs over to the water. She drinks, eats, and gets right back on the nest. I am hoping this will be over soon. If nothing ever hatches, do they just forget about it after a while? I am not that desperate for eggs that I need to put her in a cage or anything, but she has been one of my most dependable layers up till now.
I feel as you do, Purpletree. I would love for her to be a mom, but it's just not possible right now. Best of luck with yours.
PS Two of my new pullets are Buff Orpingtons, so I may be facing this again. I hear they are very frequently broody. At that time, I may try to get some fertilized eggs.
