Just last month sh3 hatched 9 chicks. But i took them away after the second day. Someone told me it was ok to slip 3 new ones under her. Went well for 16 hours until she killed them. So once they hatch ill take them away from her again. I have a dog crate i kept her in. This is the one i have tho i paid $70 off craigslist. https://www.amazon.com/gp/aw/d/B015...+incubator&dpPl=1&dpID=41SKnCxcUTL&ref=plSrch
