I had two partridge rocks go broody on the same day-two days before my chicks arrived. April 7th. I didn't have a separate area to have a broody hatch or raise chicks, so I let them stick it out. I have more than enough nest boxes. One got off the nest frequently to eat and dust bathe. She didnt lose much weight. On day 21 she hopped off the nest in the morning when I let the girls out and never looked back.
The other one, however... Was still broody yesterday. She would get up maybe once a day, eat a few specks of food, take a drink and get back on the nest. I sent her out every other day or so to walk around, eat, dust bathe, etc. I work, so I don't know if she was getting up much at all unless I kicked her out. Two days ago, I picked her up to send her out to play and noticed that she had suddenly lost a lot of weight. Yesterday I bought a rabbit cage on feet and put some grower feed and crushed egg shells and water in there. She ate and ate and ate. Last night my husband carried her out to the lawn, and she bathed, ate some grass, and tried to march straight back to the nest. I am sure that since she's been broody so long, it will take a few days to break her.
I was hoping to let her figure it out for herself, let nature take its course- but I didn't want her to die in the nest box. I have plenty of eggs, so I didn't need to break her for that reason. The chicks were too old to slip under her (5 weeks old) and no feed stores are selling chicks near me. Plus I didn't have a separate broody mama area anyway.
Next year I can use the grow-out coop and run as my broody area. How much you wanna bet that since now that I'm prepared, I won't have any go broody?
