Dear Nina.. Please forgive yourself for this terrible and tragic
accident and welcome to BYC!
You cannot be held liable for what you didn't know. The only thing you CAN do is ensure that this doesn't happen again.. ONE by learning from it so as to not repeat.. and TWO by sharing with us the possibility that some may never foresee thereby preventing even MORE chick death due to power outage in the future.. Your confession of sadness and grieving even remorse.. is a blessing to those who will embrace you and your very emotionally costly
mistake. Maybe you can suggest in a PSA or on your signature line.. that if you shut it to retain heat be sure there are breathing holes and NO heat lamps inside in CASE power returns.. being a little cool and mad is POSSIBLY better than over heated..?? Take some sort of action to release that "guilt" energy.. maybe THIS thread is good enough, maybe you will write an article to post here, something that helps you process through the emotions and become whole and confident again.
It's only by grace or luck that I have not done the SAME thing for a similar reason.. I just happened to catch the birds in time! I wasn't any better of a keeper than you. And I'm still no better. We are in this together and we WILL heal from this and overcome it together!
Once you've grieved enough, whatever that means for YOU.. Please consider bringing the Joy of new life back in and starting over. Don't let fear, sadness, despair, self blame, and doubt be the story this spring!
Maybe a jerk for mentioning.. but the cost of a "rent a coop" heat plate.. was covered in my first brood of chicks by the cost saved in electricity over the heat lamps and replacement bulbs from them burning out at the most inconvenient of time. The way they act under them is IMMENSELY different compared to heat lamps with way less fire hazard. I wish I had switched WAY sooner.
We have outages here fairly often.. we heat water on the bbq side burner and put into bottles or what have you, wrapped in a cloth.. to make our own heat packs.. they can snuggle up next to pretty well... I know this is for future reference..
I don't blame you. I forgive you, even though you don't need it. I'm deeply sorry for your loss.
