Hello! We are in the process of getting our city ordinance changed to allow confined hens. The city council voted on it, and it passed back in December. As of yet the city still has not officially made the change because there is one member who vehemently opposes chickens. She will not rest until she shoots down this ordinance change even though it already PASSED. She has drummed up a lot of fears about safety in some of the elderly city residents. I am looking for studies on this including risk factors and rates of the spread of disease if possible. I know the risk of avian flu is virtually non-existent in confined birds in this country. Are there ANY risks to neighbors if they don't come into contact with poop or feathers? Common sense tells me NO, but these people will want that in writing from a reliable source. Common sense also tells me that proper handwashing prevents illness, but common sense seems to be lacking in some of these people. Can you tell I'm pretty mad about this? Thanks in advance for your help on this!
