Thanks, all good observations! She was on the nest 2-3 days/nights and now in the crate--with straw and wood shavings and two fake eggs--two days. Do you think it's okay to lock her in except for afternoon outing until she stays voluntarily? I really want her to hatch in there for all the reasons you listed as well as those I already thought about. But I don't want to frustrate her out of broodiness since I'm paying for special eggs...
