My hen had 10 chicks, which I sold at 3 weeks because I was having some trouble integrating them with the older chicks and I was going away for 10 days and had no-one to watch them. I put her back with the rooster the day I sold the chicks, but she was only with him for two days when the neighbours' dog killed him (these are actually my neighbours' chickens, I just try to help them out because my neighbours don't look after them). I couldn't do anything for her right away because I was leaving in a couple of days. I got back yesterday and couldn't find her, but I found her and her new nest this morning. There are 4 eggs in the nest so far. So in summary, I sold her chicks on the 2nd of February and put her with her rooster. The dog killed the rooster on the 5th of February, so she was with him for about a day and half. I went away after that, and now 2 weeks and three days later I found her nest (right on the concrete floor in the corner of my neighbours' carport) with 4 fresh eggs. One of them was just layed this morning. What are the chances that any of her eggs will be fertile? She's been through a lot the last two and a half weeks. Should I set up a safer nest for her or remove the eggs?
