Reread what I wrote stupid. Birds are not supposed to smell like chemicals. The only liar is you, you are trying to defend him and it is obvious. This is what chemical spraying looks like in the middle of the night. Not rain either, because there is a tree there and when it rains that area is always dry. These chemical will dry and turn to a dust like particle. It was already investigated, hence where it came from Chyna dust. These particles binds to living tissue.
