I have 3 hens that were laying up until the 26th of Oct. I left to go out of town for 5 days and my son was caring for them. He is usually the one that cares for them anyway BUT sometimes I do have to remind him. Since I left town they have not laid even one egg. At the sametime that I was away, the weather changed and it is cooler here in Arizona, but I wouldnt think it would make adifference. I cant think of anything else that has changed. Please help me so I can help my girls!!!
