Again, I'm so very sorry. 
@Eggcessive is right, the only way to know for sure what you're dealing with is testing the birds or necropsy. Many state labs and veterinary departments offer testing and some are free.
I know culling and euthanasia are very difficult subjects, but if you have to cull, here is an article from a poultry vets perspective on euthanasia that may help you.

Culling never comes to mind when we start our little flocks and watch them grow and happily scratching about. But it is an unfortunate part of chicken keeping that most of us, at one point or another, are forced to deal with. Especially since many vets don't offer affordable pallative or end-of-life care options for poultry.
If you decide that this is what you need to do at some point, but don't think you can do it, then you may can get someone help you with it or even do it for you. I had to have my husband do it the first several times.
Please let us know if there is anything we can do. You and your birds are in our thoughts.
