Rachel, you ask a question like this, and if you get 7 responses, you are likely to get 8 different answers! Your girl's eggs are likely to remain fertile for at LEAST 2 weeks after they were last bred by your rooster. Do you have room in your coop and run for more birds? Do you want more birds? Are your current birds ageing out of production, so it would be wise to bring in some chicks this year? If all of these answers are YES, and your hen IS broody, then you could let her set a clutch of eggs. The best way to tell if she is broody: she will sit on the nest all day and night, only getting off for very short intervals to eat, drink, and relieve herself. If you take her off the nest, she will immediately return. If she sits tight for several days and nights, you could collect a clutch of eggs, and give them all to her at the same time, and let her hatch them. If you do this, remove the eggs she has been sitting on when you give her the fresh clutch. IMO, it's best to give her a place in the coop where she won't be bothered by her flock mates. You don't want the other hens invading her clutch, fighting over her nest, stepping on her eggs, driving her off the nest, or adding other eggs to it. You can pick up lots of tips on managing a broody by doing a thread search on the topic, or going to the learning center. I wish you the best. BTW, even if she only hatched one single chick, if she's a good mom, she'll take care of integration, and you won't have to worry about that aspect of it. That's the joy of having a broody. She'll do ALL of the work, as long as you give her reasonable accommodations.
