Ok so I have two flocks, my bantams and my standards. My one Bantam hen was picked on by an older hen since I got her as a young chick. She is about 5mts, has not layed an egg in forever, normal poop, eating good. Anyways, she started coughing/sneezing and almost wheezing when she breathed, a little lethargic but doing ok otherwise. So i seperated her and started her on Duramycin and she seems to be coming around great. My standards are another problem. Ok so I had 4 roosters in my coop that were running a muck and terrorizing my hens (all my hens are between 6-7mtsold) , took care of the boys last tuesday. I took them to a local butcher who does strictly chickens. Took a poop sample to the vet said they had coccidia but very mild, they said wait until the roosters are gone and if I am still haveing a problem then go a head and treat them, possibly due to stress. Well I also got some new birds (from 2 different flocks, on the same day) I usually religiously quarrienteen them for a month. Due to a raccoon problem I could not keep them in my quarenten pens safely and i had to put them in with my flock. One of the roosters has the same symptoms as the hen above (he is a year and a half old). two days ago I had my Americana die, no symptoms just she has not laied an egg in forever. Just died. then Yesterday, I had a hen who will not walk. Her leg seems physically fine, she is eating, drinking, going outside, back inside (not gracefully I might add) but she wont walk on her leg. Idk what to do!! The hen and the rooster that are sick do not have any discharge from their nose. The bantam hen has a swollen eye that is getting better but the rooster does not. My other hens have Diarrhea and I am planning on treating them for coccidia starting tomorrow but Im clueless, they seem fine other wise except the ones I just told you guys about. Any Help would be greatful!! Im praying I didnt unleash any crazy disease on my otherwise healthy flock. My hens are all between 6-7mts (I bought them as chicks) The new additions are 3 Delawares (all under a year old) and 3wyandottes (4-6mts) and 2 Maryons (1 1/2yrs) I have them in a coop at night, use sawdust for bedding (I am stripping it tomorrow and working on scrubbing it with a bleach mixture) and they get turned out in a large run during the day if they want to go out.
