Help! I had 2 chickens (hens) who were best friends, and 1 if them got killed by my friends dog. The old one keeps fighting with the new one that I got to keep her company~ Is this normal? What do I do???? I have to keep them in separate coops at night because I am afraid that they will kill each other at night. If anyone knows what to do, please please help me!! Should I get a new hen that will most likely get alone with my new one? Oh, and there are no roosters, just 2 hens. should i put them in the same coop @ night? thanks!
