My two broody moms have been raising their 4 chicks together for 11 days. They incubated in the same nest the whole time together. Suddenly today the bigger white bird (Bootsie) has started attacking the smaller bantam Japanese, Itsy. Should I separate each Momma with 2 chicks each? I do have a way to do this. will they possibly fight later when the chicks are older and I need to let them out to integrate into the flock and forage?
