One of our chickens went broody last year and successfully sat on 6 eggs, hatched 4 chicks and we now have 3 beautiful 15 week old Silver Laced Wyandotte pullets and one stunning SLW roo. She went broody again a couple of weeks ago so I bought her 12 fertile eggs this time as she did such a good job previously. I moved her to her broody house in advance and she sat well on her golf balls. 24 hours later I gave her the fertile eggs and blocked her exit from the house. The next morning she sitting next to the nest, in the food area, and the eggs were cold. I put a brick in the food area so the only place to nest would be the actual nest with the eggs, and she reluctantly sat on the eggs. Whenever the door was opened she got off the eggs, whenever she had access to outside she rushed out, picking at the wire and clucking, not happy at all. She broke (and ate) 3 of the eggs, hopefully accidentally. She pooed in the nest on three days - I wiped it off and changed the straw. During this time, I kept her locked into the house with access to outside limited to short times, although on one occasion the door blew open and I don't know how long she was out then. She gradually began sitting better and after 5 days I was able to leave the door to the run open - she is now sitting on her eggs and just going outside to stretch her legs and do her business! So, my question is, are these eggs likely to be still viable? I tried candling last night (day 6 since she was given the eggs) but could see nothing - that is my first attempt at candling. Some of them appeared mottled, some of them appeared to have a dark area, but I couldn't see anything looking like veins, and couldn't be sure the dark areas weren't my fingers! Also, what went wrong that upset her some much? My daughter thinks she was given too many eggs - she's a good size hen and I was told she could sit on 12, but is that a lot? Thanks!
