My favorite Jersey Black Giant - about 1 1/2 years old - appears to have lost weight and her comb, waddle, and area around her eyes have turned pink. I only have one other JBG, but she is still bright red. I feed them layer food and fresh water daily. They also get treats like seed, oatmeal, pasta, and bread occasionally. She is acting normal. Seems to be eating with the others. I think the color change and weight loss has been occurring over several weeks. During the last month we lost a hen to a raccoon and one to a hawk so there has been some drama in the flock. I am afraid that the color change is an indication of decline. I sure wouldn't want her to go into winter without her full strength. Any ideas?
