my broody has been sitting for 3 weeks she only seems to leave the nest when I take her off every night to try to get her to eat and drink. I just offered her a worm and she totally ignored me. when I take her off she will eat a little,very little' doesn't drink or relieve her self and gets back on the nest. I am concerned she isn't getting enough nutrition. this is the first time for both of us. Any suggestions?
