Yes, but it's usually been to come and sort out the dispute about who lays first.
The important things to notice in such situations is who got the nesting box, who left with Kolovos and what did the senior hen do after making the call?
It's often not the main event that catches ones eye that gives the most information but what the other chickens do while the event is going on and the bit afterwards.
OK, this is what happened. I should say by the way. The hen who was wanting to lay and joined the lead hen in the escort call actually was sitting in the nest before, but when the other hen came she got kicked out. The lead hen saw all this, and after some time sounded the escort call. After Kolovos came the lead hen stopped. The hen that was in the nest box laid the egg, and then the other one wanting to lay squeezed in whith her, at which point Kolovos stopped looking out for her and left with the rest of the hens, minus the lead hen. The lead hen went to the feeder and started eating just after stopping sounding the escort call by the way, although she did glance over a few times
