Currently I'm feeding rats, I recently placed a rodent pro order and included some appropriate sized guinea pigs since they're on sale. But I'm wondering about feeding chickens. Specifically is there any benefit to varying my snakes' diet with chickens along with the rodents? Are they comparable size-wise, for example if I'm feeding 100g rats would I be looking for around 100g chickens? Currently I'm feeding an adult boa (currently unsure if he's a BCI or BCC - separate issue) and a juvi retic.
