i have one girl like that right now. she just got done with brooding and raising 2 chicks for nearly 2 months. she went back to laying for about 2 weeks and now she's broody and sitting on what i think are dud eggs that i placed under her a week ago. one may be hatching any day now but i am not holding out for it. i guess i won't be selling her off if she is this reliable as a broody moma! if none of these eggs hatch for her i will give her some more and separate her so she is satisfied with more chickies to raise!
