I know nothing about chickens so any information will help. I will give you some background as to why I have chickens. We had free range chickens from down the road that started coming to our house to eat my bird feed. Of course I had to buy chicken feed for them. They would roost and the neighbors in the evening and come over in the morning and leave at dusk. Then they started laying eggs for us! Then they decided they had a pretty sweet deal and starting staying and roosting in our side barn. I love chickens, they are so interesting to watch and they eat bugs! But downside they get into everything and I'm worried about my garden this year. So now you know my history. So I had on hen that started to sit on her eggs and didn't want to leave, so I learned about broody hens. She only had 4 eggs. Since they are skittish and she nested in my other barn way up in the hay, I have been worried about her and any chicks that she could possibly have. Counted the days give or take and have been waiting. Today I saw her leave her nest to eat and there only 2 eggs and broken egg shells no chicks or yoke. What happened? I looked to see if any had fallen into a crack but nothing. Heard no peeps to confirm they had hatched. So now after my long story, what could have gone wrong? I'm very anal about animals and worried about her and her eggs. I was excited for baby chicks but also going crazy with worry. Help!
