Thanks for the advice. No need to get mad though. I had know idea I will get them switched right away. I have been feeding my white leghorns layer food since day one and they are 27 weeks old and aren't dead. Do i need to by grower feed?
The only thing that makes me mad is when people raise chickens but don't bother to read feeding instructions on the bag of feed.
Every bag of layer feed I've ever seen in the last 40 years has a statement to the effect - "Feed as the sole ration beginning at 18 weeks of age."
Nowhere on any bag of feed that contains 4% calcium does it say it is OK to feed that to chicks from day one.
Most also have a huge chart on the back that lists ages of birds and the appropriate type of feed for that age.
These feed companies employ a staff of poultry nutritionists and formulate feed for the age of bird they are intended. That includes the proper levels of essential amino acids, minerals, vitamins, fats, fiber and energy. They don't just throw a bunch of grain together and call it 'chicken food'. It is based on over 100 years of extensive research. One should avail themselves to that wealth of knowledge by reading the feed label and understand what they're feeding.
