Peachicks fighting?

[animalloverabh]

I have three peachicks, about two and a half months old, and while i let them out for a run today ( like i normally do before transferring them to the outdoor pen) the bs chick and the female ib chick pounced on each other, they then stood face to face making throughty sounds, like a frog would do and then when i walked away with the other male chick, they started to attack each other, pecking and pouncing. Before this happened, however, the male chick ( that wasn't involved with fight, went over to the female chick and the female chick was sort of bowing her head, and i've never seen this before...?

Are they just play fighting? This looked kinda serious to me lol

p.s i don't know the gender of the bs chick? anyone think they could help me?

Thanks - Alanna
