It is dangerous to leave a hen broody(unless she is hatching eggs)when broody,hens do not look after themselves,and can become malnourished. The suggestion of the broody cage is correct. Broodiness is tied to elevated body temp,the purpose of the cage(with wire bottom)is to have air circulate on their breast and underneath them,to cool them down. It is not mean and will stop the broody behavior. I have silkies which are notoriously broody,i use the broody cage technique. The longer a hen is left broody,the longer it will take to break her.I read up about the wire box but seems a little mean hopefully she will just snap out of it as neighbours wont be happy if I end ip with a rooster! Thanks for all thehelp was just worried as shes not taken two days off before and her ccrownis usually fuller
