I am so sorry for your loss. If it was my 11 yo dd (I have 4 girls), I would make her bury the chicks, pay for them, and apologize (my kids would have anyway). Even if WAS an accident (which I wouldn't call it)- its being accountable for your actions and that is how we learn from our mistakes..
That being said, that is how I parent, and obviously we are all different and none of us are perfect. I know you are really angry at this moment, and imo you have every right to be. Just try to work through it, because in the end, your family is one of the most important gifts you will ever have. Learn from this and when you have your own kids you will make better choices for them- I think all parents hope their kids will be become better people than themselves!
We homeschool also, and we have a homeschool prom. You might check around to see if there is one (or something similar) close to where you live.
I don't have the colors/breeds you like- but I could send you some bbs silkie eggs if you'd like- just pm me.
Again, I am sorry!!
