When I obtained these birds each had the hard feathering with beautiful shine that they are supposed to have. I probably got around 8 birds at that time, and all of them were fine. Three of these birds, 2 cocks and a hen, have developed soft, fuzzy feathers starting at their hackles, going over the entire breast and over the back. There is no shine, no hardness. I feed Dumor Layer crumbles feed and they also get oats, kelp, alfalfa pellets. They also get other treats such as vegetables, pasta, and bread. About once every ten days I give them a vitamin/mineral supplement in their water for 24 hours. The birds are acting okay, but clearly something is wrong and I need to figure it out before they all look like this. The only other things that I can think of that they have been given is 1/2 strength Denagard about 8 weeks ago, and I wormed them with Ivermectin topical. I would appreciate any input. I am open to suggestions as to specific supplements or basic diet that others have had success with in raising OEGBs. Thank you.
