Hi! I'm new to raising chickens, although my husband's grandfather had a farm and he's more familiar with them. We have 6 Rhode Island Red hens, about 20 weeks old now, and a Rooster, not sure what breed, Oscar is about 16 to 18 weeks old and weighs 11lbs! Unfortunately, it appears he tore the gastrocnemius tendon in both legs, vet says probably because of his weight. We're not interested in sending him across the Rainbow bridge, he's otherwise happy and healthy loves his girls and they are very protective of him. Dr. Zap suggested finding a lower calorie food for him, especially since the girls are moving on to layer mash. She hasn't been able to find anything on line or speaking to her peers, yet. Anybody have any ideas?
