Does pullet mean chickens? Well, one thing that could happen is that the rabbits will eat chickens or vice' versa. Another thing can be contrary i.e. fat rabbits and chicken may become mates, and lose their identity to be like the other kind.
I say that because I recently saw a baby horse running round and round like a lunatic with cow's calves. He thinks that he's a cow while his mother sits helplessly behind a tree. Cow's babies outnumber the baby horse, so I can understand why this is happening there. I think your next door's rabbits in minority will start behaving like the chickens in majority. More cluck-cluck on the way in rabbit accent for you.
