Hi I've hatched these 2 chicks below but they constantly fight I'm sure one male other female any idea why they fighting x the 1st 2 pick are what I think the female 4 and 5 male x any ideas welcome

How much space do they have ?

 

[CLAIREEVS1986]

Theres 4 in there and about a large dinning table size lol 6 seat dinning table lol dont know how else describe space when they get they adult feathers they got a field and coop they be free then lol. But didn't think a male and female would fight like that or am I wrong on sex. There is another cockerel in there but he dont fight at all.

They got bout 6 seat dining table space but in day I leave them run round my kitchen lol they go back in run thi g in night or if they chose got a little door for them open in the day so they can have run around for a bit. Once they grow adult feather they got lovely field to go to hatched them for my mums farm. Xx
