chickens are dying

[GmacD]

last week i went out and my 3 year old showgirl rooster was lying with his head down, i separated him from the hens and put him in a pen with food and water, the next day i came out and he was dead. for the last couple days my favorite Japanese hasn't been himself (not going outside not breeding etc) this morning he was outside, i picked him up and put him in because we are having a hurricane later. a few minutes later when i when to get there eggs he was on his back twitching. when he stopped i picked him up, he was limp. i put him on top of some towels. I'm not sure if he is dead (if he is cold and stiff when i go out in a little while then i will bury him) and i have no idea what could be killing them

they are free ranging and have layer ration in their house

i introduced about 20 chickens to the flock a month and a half ago but the person who i got them from has not had any problems

You can be fairly certain, even without showing signs of illness, one or all of your new birds has passed something on to your older flock.

Without a necropsy it would be hard to tell exactly what the birds died from.

If you are having temp changes with the hurricane you can bet your chickens are feeling it.

3 weeks is not long enough.

With both of your chickens having died so suddenly they most likely picked up something from the new birds.
