I am so excited that Ihave a broody hen trying to hatch 3 eggs. I have her in a seeparate cage and all comfy. I have a heat lamp near her but not too near. The temps are in 40's during day and maybe into mid 30's at night. Not freezing but certainly cold. Should i bring her cage into house until peeps are older? Should i just move heat lamp closer? Not sure what is best. This is my first hen hatch.
