I have a Spring born Astralorpe and she has been a great egg layer until about 5 days ago. She had laid an egg five days ago and then I found her appearing to lay again the same day that evening. Ever since she has been in the box straining to lay with no results. I've put her in very warm water for 20 minutes 3 times and have also brought her inside in a quiet dark place all day yesterday. I've felt inside the vent area and her abdomen and can't palpate an egg. Any ideas? I don't know how long she can go on like this or if I should get her into the vet. I am so worried about her so any advice would be welcome. * After much stressing, it seems she is broody right now and she was given 3 fertilized eggs to sit on this am.
