The coop door was left open on our coop, the chickens (we had 16) 13 hens / 3 roosters got out and our dog killed 10 of them.. I AM SICK there is 1 rooster left he is limping / but there is one hen that I am pretty sure will not be alive tomorrow morning the other 3 are in the coop. they were just 3 months old, all very very healthy I can't even explain how I feel we had just doubled their outside pen to double the size, things were going so good what would you guys suggest as far as replacing the ones we lost, I hate the thought of starting over from 1 day old chicks, can we get 3 month old hens? and if so how would we go about putting them in the coop with the others. I never realized how close I had become to all the ladies until tonight, I feel so awful, it makes me sick, and it isn't our dogs fault to him it was just a game. Any suggestions?
