Ever since yesterday my hen has been setting behind my dog igloo. I'm pretty sure she is a black sex link so I didn't think this would happen. At first I didn't think she was serious, but I went to check on her and shes in the same place she was yesterday morning.. last night I gave her an egg she had laid a few days ago from the fridge. This morning I lifted her up and I'm pretty sure on the fact that I only saw one egg... she had stripped a lot of feathers off her underside, and it was really warm. So I'm starting to think she really is serious, but ONE egg! will she lay more ? or do I have to give her more? I do have two other hens that will lay an egg today I can give her those, I also have A LOT of fertile eggs in the fridge, but they have been there for a while and I don't want to risk giving her some that may rot, so what would be the best? thanks! haha sorry for basicly writing an essay, the chance of having more chicks gets me excited!
