I lost my sweet Buff Brahma yesterday. I only had 4 chickens, all around 6 months old. Late last week I noticed my Brahma was off by herself and laying around more. I thought that maybe she was getting ready to start laying soon even though her comb hadn't started to get red. Over the weekend she started looked more puffed up and wasn't herself so I separated her from the rest, made sure to give her more vitamins and that she was always close to her food and water. Finally yesterday morning she died. I'm not sure why. She went downhill so fast that I'm not sure what illness she had. She was supposed to be vaccinated against Mereks, I did order some medicine for coccidiosis, but sadly it didn't get here in time. I'm not sure if I should treat my other birds just in case or wait to see if anyone else gets sick.
