Chicken Danz,
I am so sorry about your llittle goose. I will say a prayer that it is able to get rid of whatever it has inhaled. Losing any pet is never fun. People probably think me silly when I mourn the loss of a hen from my flock. But hey...these aren't their **** chickens.
Don't let the creep on eBay ruffle your feathers. Just bless it and move on. It takes all kinds I suppose. In cases like this I just let eBay know the circumstances and common sense should prevail.
The problem with eBay is they rule in favor of the buyer, they're right no matter what, so that person will get their money back whether it's right or wrong. That's why people get burned out selling on there, especially eggs. Even if you put a disclaimer on your ad they still will rule for the buyer if they complain.
