So my 'maybe' rooster started crowing, and I found him a new home. At work, we have had a hen that has been hanging around the shelter for about a year and a half (we think she is about 2 years old), and they convinced me to take her home, because I had room for another, now that I don't have my rooster anymore. I did, because she seems to be a good layer (about 3 eggs a week until she went broody). Anyway, I introduced her to my other 3 girls (all about 6 or 7 months old) last night, and they are picking on her. She is a little smaller than they are, and so far, they have bloodied her comb. Should I just continue to keep an eye on them, and if it gets worse remove the new one for a while? Any other advice? BTW, They live in a chicken tractor, so the only way I could seperate them and them still see each other is to move the new one to a large dog crate and put it beside the tractor. Thanks for any help!!
