Keep forgetting to mention a behaviour I've noticed recently that cracks me up.
The pullet wants to lay an egg. If she and the boys are right by their run, she'll go herself but if they're further away she wants to be escorted back to the run (but left alone inside the coop to do her thing, thankyouverymuch). She makes this known by doing an increasingly agitated version of the "laying an egg" cluck and pacing about if one of them doesn't go with her straight away.
Black and white is trying his best to be a good cockerel - he always inspects the nest box when I put fresh hay in it and does the screechy nest approval growl, but he doesn't quite understand what's so special about that nest box. If they're foraging in the empty run or another bit of the plot, he usually wants to stay there and finds what he thinks is a good place nearby for the pullet to lay her egg. Last time he just about managed to cram himself into the pet carrier I used to use for the chicks. He'll do the nest noise, she goes to check it out, they have what looks a lot like a minor argument about whether or not it's a perfectly good place to lay an egg and why can't she just go here?! She eventually decides he's an idiot and stomps off to her preferred nest with him following behind.
