Yes when I tried that it didn't really work the hen still was broody and continued for another month.
The best way to break a broody is to put them in a pen with a rooster. Until she stops her broodiness.Or when she stops being fat and making purring sounds.
This worked for me I would have a broody hen throw her in the broody pen and once I saw an egg I would let her out back with her friends.
The rooster makes them submit so they go back to normal.
Also in the spring broodiness is CONTAGIOUS so when you have 1 it will turn into like 3-5 depending on the breed and how many chickens you have.
I would have up to 10 hens in the broody pen and they would go back to normal in about a week depending on how far the broodiness had gone. The sooner you catch her broody the quicker the affect.
Hope this helps
