Its a very good business indeed, the whole city or the country to be honest doesn't have a decent chicken place apart from "chicken cottage", are you doing like nando's style or KFC?
I think its better if you buy it from the slaughter house, one thing you need to pay attention to that the prices are like roller-coaster just one night the chicken breast jumped from 4.50LYD per Kg to 6 LYD per Kg.
Check many slaughter houses as they vary depending on the quality, hygiene and stuff like that.
I recommend "Attahrur" Slaughter house, its very modern compared with the rest, their chicken taste better and look brighter and cleaner on display, very white skin not like the other yellowish colours and discolourations.
"Attahtur" excuse me for the spelling, their outlet is located on Al fateh St. driving past Mitiga International Airport, drive straight on the first roundabout 3rd exit, at the second roundabout take the 2nd exit u will find it just few meters on the right hand side, with the chicken sign displayed above the outlet.
here are the coordinates on google earth
32.893471,13.345578
any help you are welcome to contact me
cheers
