I had four rooster who were too rough with my layers so I sent them- two at a time- to my grandmas house until I could find them a new home. I recently brought home three roosters back from my grandmas flock. There was originally 4, but one recently died. I brought the two Easter Egger roosters to my grandmas because they weren't getting along with my other roosters. They were at my grandmas for probably 2-3 weeks tops. One died on Tuesday night, my grandma says he died of a heart attack. He just fell over and died but he was 5 months old so I think he died of an illness because they don't keep things clean whatsoever, nor do they care or check on their chickens. They are very old school and don't keep up with proper cleaning or care practices for the chickens. The other two roosters, a silver spangled Hamburg and a buff brahma, were only at my grandmas for one day and night. So out of the three remaining roosters, two are sick with different illnesses. The buff brahma is healthy as far as I can tell. My Easter Egger roo is acting normal but has a slight cough and clear snot coming from his nose. He has a very good appetite and is constantly eating. The silver spangled Hamburg is much worse, at first he had watery eyes, one swollen area under an eye, yellow snot coming from his nose, rattling noises when he breathes, keeps his beak open to breathe, and has a yellow mucus type thing lining his top and bottom beak. He doesn't eat or drink much and just wants puff up and sleep. The silver spangled Hamburg has been sick since last Saturday. He doesn't seem to be improving much- he still rattles, has some yellow snot and has the yellow mucus in his mouth. I went to the vet- who is not a bird specialist- on Monday and he gave me some antibiotic (doesn't say what it is on the bottle.) So the Hamburg has been on the antibiotic since Monday and the Easter egger has been on it since Wednesday. I'm afraid the Hamburg has wet fowl pox and the Easter Egger has infectious bronchitis. This terrifies me because I have 17 other chickens in their coop and I'm terrified that I will accidentally give it to my flock. I check their noses and eyes every night and I haven't seen anyone that's sick yet. However when I let them out today I saw my Australorp had clear snot coming out of her nose but my whole flock acts normal. They are all eating, drinking and laying. I read on a forum on this site that shaking heads indicates illness and some of my chickens where shaking their heads but I'm not sure what from. I have sand as flooring in my coop and I clean all the poo out every morning and night with a kitty litter scoop. I didn't know if the the dust from sifting the sand could give my Australorp the runny nose or not. I'm praying that's all it is and that she hasn't gotten the infectious bronchitis. I try to keep things clean as possible and always take care of my healthy chickens before my sick chickens. I wash my clothes and gloves everyday and wash my hands constantly. I've kept the sick Roos in my garage in separate cages. I've also cleaned everything in my garage with Clorox in hopes that I don't spread the bronchitis. Today I gave my Roos one cc of the antibiotic and rubbed vet rx on the nose and in their beak. I also gave them electrolyte water. I swapped the yellow gunk from the hamburgs beak. I put a couple of drops of vet rx in one of the waterers in my coop but I'm not sure what else to do for them. I was going to give the three roosters to someone to add to their flock but I'm afraid I can't do that if these Roos live. I will be upset if these Roos die but I will be crushed if my entire flock gets sick and dies. Obviously I'm a big time worrier. I just love every one of my chickens and I will be devestated if I lose any. What can I do the keep my flock healthy and try to save my two sick Roos? I bought terra-vet 10 but I'm not sure how much to put in one gallon of water. The instructions are too confusing and the measurements are in mg so I'm not sure how much to use per gallon. Please help!
