I do not recommend brooding chicks and keets together due to the issues that imprinting causes later on. It is best to let the keets grow up as guineas.oooh you have chickens! do you have chicks? throwing them together is a big confidence booster for the guineas. it only works if they're similar in size though...eitherway, I'm sure they'll mimic the older guineas when they grow up, so I wouldn't be too worried!
