Hi All, My mother Japanese Bantam x English Bantam has all of a sudden started chasing off 3 of her own chicks. They are only 4 weeks old. She is protecting the other 9. What gives? They have plenty of room, plenty of food, etc. I can't tell if the rejected chicks are males - I thought maybe that was it? I'm thinking I should take those 3 out of the pin (it's large - about 20 x 20 feet) so she will stop attacking them. However, I don't really have a protected place for them. Any suggestions would be appreciated!
