That's a pretty standard ordinance for a residential lot. You should be limited to enough birds to feed one family. I think the 5 acre limits are too generous. 50 birds in a residential area is nuts. At 50 birds one is either selling eggs, meat birds or cockfighting. . There are also no rooster restrictions at 5 acres.
There needs to be more wording. Eliminate any grey right up front. What is waterfowl? What is gamebirds? Ganders, petcocks and guineas? They will be noise violators day one so check them off the list to start. What's an enclosure? How to deal with violations and complaints... I obviously don't see a problem with the first draft of this proposed ordinance and see the need to add more teeth to it so everyone, even the non chicken owning neighbors can live with it.
