...when you are delighted to hear a baby crow respond to the Grown Up Rooster, from the part of the run where the Littles are housed, on your way to let them out in the morning. And then you realize you can't tell which one did it. So you stand there talking to the suspects, for a long time, hoping it will do it again. And start thinking, "Oh, I'll need more ladies, now that there is more than one roo...."
And you're already 8 chickens and 2 ducks over the legal limit AND you've not told your landlady how many chickens you actually do have....
....plus one of the pullets is broody with 3 eggs under her AND you can't figure out why you just bought an incubator when you SWORE you weren't interested in actually hatching any chicks. Ever. But you've read the instruction manual about four times already, and found a place to put the thing.
