The link is working for me. Since you are in another country, I don't know if that makes a difference to what you are able to link to. I'll add a few below, maybe one of them will work for you. You can also just search online for Fowl Pox and see what articles come up for you.

It worked and i read some of it and you right it the dry one and it hasnt infected any other bird so it okay till now i guess and the one that got infected is doin okay. She actually lays every day

You have to put the welfare of the birds FIRST. Not profit. Period.

Your are right but the birds are doin good so far and 8 birds per square meter myt be a bit over but not life threatening
