I have a 8week old chick who is not well, she is still moving about, but she is all puffed up and dosial if she doesn't have to move. The flock will move around the back yard but she gets left behind. She tries to keep up sort of does but just puffs back up and sits their chirpping. The flock hasn't rejected her yet, she has been like this since last nigh, but she was fine during the day. Mum and Dad still accepts her. I thought she may have improved over night as they all huddled in the coope, she hasn't worsen over night, but not getting better. She was the runt of the litter, but in saying that she is not all that small now, she has held her own and kept up in size if not grown to be nearly the same as the others. She is eating and drinking. I couldn't tell you what the poop is cause I never really see it. Their bedding is just straw. I don't feed them anything but grit, chook food and the occasional oats for a treat. Mum from day one has been great at guiding what they can and can't eat, so I'm not to sure if it's something she has eaten. Do I intervene? I wouldn't forgive myself if I didn't try something! Please can anyone give advice.
