Ok I cant remember when I got them. But they have to be at least 2-3 months old if not more. Theyre heavier than anything, but not as big as I had thought. I would feel horrible killing something perfectly healthy, or even giving it to someone who I know would do the same. They all walk fine and everything. They all look like pullets. One I noticed when I picked it up the other day it was breathing funny and kind of weezing. I dont want to kill them....lol....help? advice?
