My hen, Starbucks, was laying regularly and has laid several double yolk eggs after starting to lay in early September. Since then she has laid several double yolk eggs. However, about a week ago I saw her lay an egg without a shell after she had climbed up to the roost for the night. Now, she isn't laying every day like she was. She hasn't laid for two days and this morning she wouldn't come down from the roost. She is usually my first one up. Could she be egg bound?? Her abdomen doesn't feel hard or swollen and she is eating. I haven't added additional calcium through oyster shells or anything but will be going to get some today. I haven't performed an exam of her vent to see if she is egg bound but I don't think that is it, because she doesn't seem to have any other symptoms except for lethargy. I will try that if necessary but not exactly sure what to do or what to feel for. How else can I know if she is egg bound? Is there any other reason a hen wouldn't come down from the roost in the morning? Thanks!
