I went to go check on my girls this morning and discovered what I think is our first "egg" My girls were born around the first of December so they are about 4 1/2 months old. We hadn't switched to laying crumbles yet, we thought they wouldn't be laying eggs for another month or so at the soonest. Is 4 1/2 months old early for laying eggs? What you see in the picture above is a ceramic egg we put in there to gauge their behavior and nesting tendencies, next it to we found this leathery skin looking shell, I presume, and the ceramic egg covered in yolk. I'm guessing they laid this egg at night since it wasn't in a nest box it, looks like they pooped it out at night while they were sleeping based on where we found it. So my questions are, does this mean they will be laying eggs regularly soon or could this be a one off? If we start them on laying crumbles right away how long will it take to correct any calcium deficiency? Is there anything else we need to prepare or keep in mind now that they are laying?
