I just got started a week ago. I was so proud that my 4 chicks made it almost one whole week. Tonight in a matter of 3 minutes my pit bull mix got into the coop and took one of my pullets. The other 3 were fine but we found the 4th in her dog bed inside. I read up on dogs and tried my best to train her to stay away from coop. I thought it was going well. I can easily secure this part she broke into. You live you learn I guess. Why do I feel so depressed I lost one? Do I need to toughen up? I' have to explain to my 3 year old daughter why there are 3 now. Should I get another chick to replace or let the 3 remaining go on together just them? Sorry for rambling, but I was woken up in middle of night from commotion and now I can't sleep
