Rebellious Rooster

We have a few animals here on the base. A few sheep, a few chickens and a mad rabbit. I'm not usually a detester of animals but we seem to have a few special ones that don't make friends easily.
The rooster is confused and likes to crow at all hours of the morning, noon and night, no idea how you can train him to recognise daybreak?
The rabbit is a particular pain. It was a left over pet from a previous occupant and now just wanders around the base. It likes to follow people, run around you in circles and then pee on you. That was until the rooster arrives and now it follows the rooster around all day trying to do rabbit things to the the rooster.
Personally I think they'd both make a nice contribution to a potjie.
