my chickens died today :(

I had 4 chickens 2 ginger and 2 black and my sister forgot to put them away into the coop, and the foxes got them, and there are feathers everywhere. :( I can't stop crying I hate my sister :(

My mum said we'll get some more in the spring but it won't be the same :'(

here are a few pictures of my chickens before they died ...
