Apart from the boring 2 dogs and a cat, I mean.
We have a normal looking hen, and then three of these dinosaur-looking chickens that have just hatched recently, and their mum, who is smaller than them.
They're strange as buggary, and apparently the 2 boys will end up mating with their sister soon.
Advantages: you don't have to waste all your non-meat food. Just throw it out for them.
Disadvantages: they shit on the floor all the time, and the hen scares pizza delivery men.
