Hi - any help would be appreciated. I adopted a hen sitting on 15 eggs (one is a double - super big) - she nested in a horse stall that had a horse moving in!! I've had 5 RIR hens for about a year, and everything has gone well with my egg layers, but i'm not sure what to do about this hatching process and chicks. I have the hen/nest in a 4' cage, with thick layer of pine shavings, sitting in middle of my very large chicken run. About a week ago, one egg broke and dried yolk is on some eggs. About an hour ago, the fist chick hatched and is under hen with all the eggs. I put starter feed out, and water w/electrolytes. My three main questions are: 1) is the think layer of shavings the right thing to do? 2) how do i now if i should intervene? and 3) I understand the twins aren't likely to make it - but there is a video on youtube of a lady breaking the shell and they survived - apparently they don't get enough food and aren't strong enough to break free? If i try this, how do i know the right timing - i have no idea when these eggs were laid....i mean, i don't understand how one hen is sitting on so many eggs naturally?
