Here is a picture i took today, i noticed a bit of bullying yesterday, while i was watching them this morning i noticed two hens taking turns at attacking this one, they have all been together for around 7mth with no problems.
Ive also had a hen bird attack a cock bird, so bad infact the cock bird nearly died and they where brought up as chicks together, nothing is plain sailing with Jap quail, they might be little but they are pure evil with each other from the minute they hatch.
