You are in a warm climate,,,   so at 5 to 6 weeks age, they can be moved into outdoor coop.   
Flight feathers are only trimmed when chickens are full grown,,, and they are escaping over the fence.   I did trim some of my new addition grown hens,,,,,,,, because I did not want them escaping over my 6 foot fence.  Once they were settled in, and their feathers grew back,, I never trimmed them second time.   There is a good reason for chickens to be able to fly...  To escape predators,,, and to reach their roosts without struggling. 
I know what you are seeing currently. Your baby chicks are flying out of their brooder.   When they will be in a larger run area,, they will not be taking flights.  Make their run interesting with odd objects inside,,,,, so they can hide,,, as well as explore.  Temporary boxes, chairs, crates are just some things to consider. 
Ask anything else you are not sure of,,, The whole BYC community is here to give answers.
WISHING YOU BEST,,,,,,,,,,,,,,,,,,,,,,,,and
