I have had hundreds of chickens since I first got chickens. Almost all of them are safe and content while they live out their natural, carefree lives. And yet, the few sweet birds I've accidently caused the death of still haunt me. I so wish I could go back in time and rectify my mistakes. But I can't; all I can do is learn from my mistakes and do my best to care for the ones I have now, and the ones I will have in the future. Yes, I fully understand your pain. But IF you accidently aspirated her, it was only because you were trying to help her. You will learn much if you continue to have chickens. And I sure hope you do, because any chickens you have now or in the future are lucky birds indeed. Not because of mistakes you may make, but because you loved them in the first place.
