I am new to raising chickens. Ive had my 2 hens and 1 for a year and never had any problems. I live in south Florida and the heat and humidity have been brutal. Over 100 every day. They have been turned out to run for more than a month but now they have stopped eating their scratch. They eat everything except the cracked corn which makes up a large amount of the feed. And are constantly acting like they are starving. They go as far as to climb in the dog pens to eat dog food and attack the cat to eat his food. Is there something else i can feed them that is not outrageously expensive?
