This approximately 1 yr old hen was stricken with what I believe was a milder case of botulism. I have been posting about her here https://www.backyardchickens.com/t/681695/heat-exhaustion-or-other-legs-paralyzed/10#post_9242198 . She is definitely going to take some time and effort to heal (if it's even possible). If you might be interested in her let me know. I'm located in the Kansas City area.
