So this is our 3rd year with chickens. Last summer we had a hen go broody and just left her to do her thing. It was right when we had a heat wave of temps of 90+ for a couple weeks. None of the eggs hatched. Well right now we have another hen sitting on close to 20 eggs. She’s been sitting for close to 3 weeks now. For the last 2 weeks I wasn’t home and able to check them or anything like that. Tonight I was able to sneak 4 of them from her and 3 for sure are fertilized when candled (completely dark). I know it’s getting close to hatching time if they do this time. What are my next steps? Close off access to her from the other hens and let nature run it’s course? I did notice tonight one of her “sisters” was sitting right next to her in the coop. So not sure if she’s helping a bit or just found a cozy place to sleep too. Any tips and advice is appreciated. Thanks all
