There is a saying on here you need to adopt: SSS Shoot, shovel and shut up. If you need to talk about it come on here and talk to us; we understand.
You have my sympathy because I know it was hard to kill cute little babies but almost every post has reaffirmed you decision. It wouldn't have been fun to have to cull your birds after the babies got hold of them either. People who don't raise chickens and have not been in that situation cannot possibly understand.
PS thank you for reminding folks that nocturnal animals get insomnia too. I've seen coons, fox, owls, etc in broad daylight looking for free meal.
