Hello.. sorry if this has been covered alot.. i have 8- 7week old guineas..I am feeding them Dumor 24% crumbles... i also have 12-13 week old barred rocks and white leghorns... is this high protein food ok to feed them? I also have medicated chick start.. which would be better to feed the older chickens?? also have layer mash... i hate buying a 4th 50lb bag of poultry/finisher.. can they eat the 24%? thank you in advance...
