She might, she might not. Broodies can be nutty sometimes. Ive had some that want all the chicks, somw that do try to roost again on day two (she's an idiot amd will not be setting anymore), one that only wanted 2 chicks ever. She would hatch more and take in orphans, but leave babies until she was down to 2 again (she also will probably not be allowed to set more) and one that halfway through brooding, adopted a 5 week old that was being weaned by another hen, and then tried to kill her own eggs when hatching (but she remained setting on them even after adopting the 5 week old)
