Cynthia I am so sorry, I know how you feel. I lost so many in a short time. It was so depressing, there were days I did not want to go outside because I was afraid I would find another. First I lost Evelyn my dark brahma, then my GL cochin, then my blue amer. rooter and then the saddest of all, Alma. It stinks and I hope your guys get better soon.
It seems that there is some relation between the rooster's comb health and testosterone/androgen. I'm wondering if your rooster could use some kind of veterinary steroids since he hasn't been very active.
I pray Zane, Lorelei and Ruby are soing better this morning? We are here for you and hope Diana can help as she is always full of good knowledgable advice. I pray she finds the answer for you.
