I'd say yes, if you can manage to create an ecology where the narrator is actually wrong about the Domestic Dragon being a chicken-dragon, for all that people keep them for eggs and meat. I like the instruction upthread to mix it up a bit: have dragons take over some niches mammals or true reptiles have, and have mammals/reptiles/fish cover some niches instead of a one-to-one dragon-species for bird-species swap.

(Also, have you read A Natural History of Dragons by Marie Brennan? It features an alternate world where there are many types of dragon. The main character is biased towards charismatic megafauna, but she mentions small garden creatures like 'sparklings'.)
