I have chicks (well there almost 5 months old now, but they look like 3 month old chicks and not growing as fast). I used Blue Seal Grower Pellets and the bag is almost gone and it seems it made them grow alittle bigger. Should I just stick with feeding them the grower pellets? It has 15% protein.. Or should I just buy egg layer pellets that are like 18+% protien? I need know the fastest way to make them grow.. Thanks.
