My chicks are now 19 weeks, two have been crouching now for a few days, just noticed the behavior and saw someone else post about it. Today found the first egg on the poop board in the sand, soft shelled tan, somewhat squashed but did have yolk and white. My question is this. When I pick up the crouching hens (barred rock and wyandotte), both their vents are gaping open, is this "pending" behavior or post egg behavior and how can I tell who laid the egg?
