Well...I don't want to come off the wrong way...but...there ARE a couple of things to consider.
First off...you don't KNOW that's where the eggs are going.
Secondly, maybe in her head she's gathering eggs her mama has sent to out to get.
Another thing to consider: maybe she really needs those eggs. If she knocked on the door and asked...what would you do? I know...it's frustrating, aggrivating, and downright disrespectful when people take YOUR property!
And I have no idea whether any of this applies or not...but..at the end of the day...you should step back and at least consider this...and remember...they are just a few chicken eggs after all.
