Everything I kept finding was for Wisconsin for some reason despite looking for Maine.
I'm pretty sure that one is in Maine, because I clicked a few of the headings at the top and got a page talking about how nice this little town in Maine is.
Okay, but where do I find poultry? I can't find anything about it.
I skim-read the whole thing, and searched for a few specific terms, but I did not find any mention of poultry or livestock.
What I did find:
--a list of four zonings
--Agricultural/Residential District list of allowed uses includes "farming"
--Commercial District allows "All uses allowed in the Agricultural/Residential District, and in addition...."
--Industrial District allows "All uses permitted in the Commercial District"
--Resource Protection District says to see the Shoreland Zoning Ordinance, which is available by another link from that same list
The Shoreland Zoning Ordinance lists several zonings within it.
It has a definition of "agriculture" that includes poultry.
The table of permitted uses says that agriculture is allowed in some of them, and allowed with a permit in the others.
So if you're looking for information about a particular property in that area, you would need to check which zoning it is in, then check the details for that particular one.
The main zoning ordinance keeps talking about things that need a "CEO," which I found defined in the Shoreline Zoning Ordinance: "permit issued by the Code Enforcement Officer."
