Hi all. I just. Finished my coop and run. Have 2 buffs, 1 Plymouth rock, and 1 mix. All 7 weeks. And 13 in incubator on day 20. I fear my 13 are not going to make it last night son opened incubator not sure for how long but now have no movement or chirps. I'm so sad I've been working so hard. Can anyone give me some advice.
