I've had chickens while living in Arkansas. Had very few problems. Certainly none that were serious. I'm currently living on an island on the Caribbean side of Panama. I have 9 hens about six months old. They've been laying for about two months now. (Seems early, but my best calculations) I lost one about six weeks ago. All my reading leads me to believe it may have been due to Merek's. I am not sure of the quality of feed here. If I ask for chick food, I get powder. If I ask for layers food, I get a mix of mostly corn. If I ask for just chicken food, I get whole corn. So I am feeding them powder chick food. I supplement them as a treat with layer food that I ferment. I also add ACV to their water as well as poly vi flor (no iron). I also offer them oats, rice, fruits and veggies, but they are not interested in produce at all. They love the fermented grains! I also will give them cooked egg for protein and add their pulverized egg shells in with their food to which I also add powdered garlic on occasion. I have one girl (Gigi) who started limping during the time I was experiencing possible Merek's which was the initial symptom. Gigi has not shown any further symptoms but still limps. I'm fine with that. A couple others I think I notice they breathe like they may be congested. But no other symptoms. Now I've noticed that many of them have a stripe of bareness on their abdomen from breast to bum. Otherwise they seem healthy. They're not thin or ill looking. I just don't know what is happening or what else to do for them. A vet is not really an option as the locals do not value chickens as pets but as mere livestock that are usually just on their own to fend. So it's me and my girls against the jungle. Any ideas/help would be greatly appreciated.
