We will be gone for a week (7 days) during September. The weather might be hot or it might be cool. We won't know till it gets here. It is Missouri so it could be 90 on day and 70 the next. Anywhoo.... We will have someone come check on them at least a couple times during that week. My questions are about egg collection. If it is mild weather 70's or not super hot will collecting them every 2-3 days be ok? We currently only have two hens laying, but the other two pullets could start by then. Will the hens do anything, like push the old eggs out or anything? I am totally new to laying hens to tell me what I need to know about the egg part of it. I know all about the food/water/house part of leaving them.
