I am not sure if this is a correct answer to your question, because i am no expert on fowl, but I am not aware of birds ever having gill slits in there formation. Humans have slits that have been misconstrued to be gill slits but those are there to help with the formation of your neck and ears.
I imagine that the two cases are related, but, like I said, I am no expert on birds.

How many gill slits does a leopard shark have?

All vertebrate embryos develop gills during one of the many growth phases in their development?
It would be more appropriate to say that all vertebrate embryos develop pharyngeal gill slits during one of the many phases in their embryonic development. This is because while gills are specifically present in fishes, pharyngeal gill slits are a general chordate feature.
What is the function of the gill slits?
Gill slits in sharks and rays help to funnel water into the gills, which empty into the pharynx and eventually the lungs.
Does a coelacanth have gill slits or gill flaps?
Coelacanths have gill flaps rather than gill slits. They possess a unique structure called a "gill cover," which is a fleshy flap that protects their gills, unlike the more traditional gill slits found in many other fish. This adaptation is part of their ancient lineage, linking them to early vertebrates.
The openings in the throat region of a fish that lead to the gill chamber are called?
The openings in the throat region of a fish that lead to the gill chamber are called gill slits. These slits allow water to flow over the gills so that oxygen can be absorbed and carbon dioxide can be released.
What is a pharyngeal gill?
Pharyngeal slits are not gill slits. They are filter-feeding organs in non-vertebrates, and are used to strain matter and food from water.
How many gill slits does a cookie cutter shark have?
A cookie cutter shark (Isistius brasiliensis) has five pairs of gill slits, which is characteristic of most shark species. These gill slits allow the shark to extract oxygen from water as it swims.
