Dying chickens...need help

4 chickens over 3 weeks.  one at a time.  Huddle up in the corner and dead by morning with no other signs previously.  Once noticed at least one had a bump/growth below eye above back of the mouth.

I have been told maybe Laryngotracheitis??

any experience or knowledge about it?    I have read the birds are carriers for life?  do i need to cull them all?

any help appreciated

im not familiar with this disease but im one that when there is doubt or question, i would clean house.

How many chickens are we talking about here? I hate to sound harsh, but when in doubt, cull them out. If you add more to your flock, you run the risk of the new additions dying too, plus if it's something fatal then leaving them to die may be the less kind approach.

4 have died...there are 27 more still.    I am really not sure whats up....some other folks told me it may be cocci?    I am new to chickens.....will cull them all if its the right thing to do but dont want to jump to killing 27 (24 hens)  if not necessary

thanks

oh yeah they are 15 weeks old now.

With that many, maybe taking  one to the vet would be in order for a proper diagnosis. If you don't catch one while it's sick but before it dies, I'd call the vet and ask if you can bring one that died in so you can get some idea of what's going on. Just make sure it's a vet that knows chickens. and isn't going to want to charge you an arm and a leg just to give his/her opinion.

yeah not too sure I can even find a vet that knows about chickens....

That's a shitty position to be in man. I'm really sorry I can't be of more help. 

do some research on cocci and see if the symptoms match what you read.  but beware many fowl diseases have similar symptoms.  sulmet and corrid will help with cocci.  apple cider vinegar is a good natural preventative measure. but if you have a full blown case of cocci, it wont help. 

some will get it, and still survive, but it takes such a toll on them, that they will never be much.  a sure sign of cocci is bloody manure, but not all strains of cocci causes blood.
