My fertile eggs should be here any minute. We're putting the finishing touches on the dog crate/broody house. I just have a few questions: -how long to let the eggs settle once they get here? 12 hrs, 24 hrs? -should I candle them when they get here to see if they're good or wait until they've been under her a few days? -how many should I put under a bantam? I ordered a dozen eggs but only one girl is broody. Thanks in advance!
