There was a bit of an odor in his trailer (he had a trailer just for the parakeets and hatchling birds and some breeder birds), but, there were hundreds of birds in there, some of which were chickens (he had a few adult chicken breeders in there too). But, all in all, for the amount of birds he had, it wasn't much. The button area didn't have an offensive odor, it was just a cumulative scent from the whole "operation". All in all, it didn't smell half as bad as the petstore... So, I'm going to say no, as long as you keep up with them.
