We have a broody mother sitting on 13 eggs that have been fertilized. I've candled one and found that it was full so we have some chicks on the way though I don't know exactly how many. We want to let it happen naturally since we have a sitting hen but is there any tips for me so I can increase their chances of survival? I'm a little worried since winter is coming up but I'm sure mother nature can handle it. Just let me know if there's anything I can do without interfering with nature.
