I have a young silkie hen (about 7-8 months old) who has been laying consistently for about three weeks. In the last week she has been taking increasingly longer time to lay, up to several hours, and seems to be straining a lot, even after laying. Yesterday she sat all day, all last night, and is still sitting, and occasionally straining. She seems to be calm most of the time, but will "cry" a bit at times when her body is really straining. I'm keeping her warm and forcing water into her. I've also started giving her just a tiny amount of castor oil. Her vent appears to be just fine, and I can't detect an egg. I have not yet tried to massage her vent with oil. Is there anything else I can/should be doing for her? I'm concerned about her current state, but also that she seemed to be laying just fine, but has been demonstrating increasing amounts of time just sitting and occasionally straining. Thanks in advance for any advice you can give me that will help.
