Hen thinking again about going broody!

[hcammack]

my little delaware was sitting for a day last week and then another this week she is really thinking about going for it ! She was sitting on 4 wooden eggs then I put 1 plastic egg and a golf ball she got up to eat and then got back on and covered them all. She is off the nest now roosting with the rest of the hens. Is their a way to send he into the full broody state I just want her to hatch a few chicks or go back to laying?

Thanks in advance,
Henry
