Lessons are learned in various ways. Heck, I just lost 20, yes 20, birds on fathers day... and I know it was my fault, but I look at it this way:
Everyone and everything with a life goes to heaven, everyone who is good.
When God wants someone to leave earth and go to heaven, he will take them. There are various ways he can do that. Through people even.
When 20 of my birds died, God wanted them, so he chose them to die through me.
Yes we feel terrible, but there are lessons to have learned, and some may be painful and heartbreaking.
Do you know what most poultry birds in America are used for? Meat. So be proud that you raised your birds for pets and eggs. They had a good life, and sometimes we just can't afford to take care of them, so we must sell off some, and we are never going to know what becomes of them.
If the man that bought them must kill some, just hope he keeps a bunch for eggs.
I'm sorry.
