That's what I'm doing with my golden lace cochin banty right now. She was so broody that I finally let guilt get the best of me and stopped taking her eggs. She was going to go through the summer being broody and make herself sick, so I've let her have some eggs. I give her some food right in the nesting box and she gets off occasionally for water. I thought about taking her and the eggs and putting them all in a cage with food and water, but thought that would be more upsetting to her. One of my hens, a polish frizzle, was successful in hiding her egg clutch outside from me. I think she got wise to me taking her eggs, and devised a plan. One morning I saw her trotting out from between the hollyhocks with her eight fuzzy chicks. One way or another, they'll find a way to sit on those eggs!
