Hen chicks sparring??

Raising meat birds and laying hens together, we have 37 in this coop. Planning on making an outdoor run soon.

My question for y'all: is this normal play fighting or do I need to give them toys ASAP? I have given them a couple log perches that a few of them seem to enjoy. I have one crossbeak hen chick, so I have been giving them a water/feed mash to help her but every birdy loves it too.

Any advice would be appreciated!
