ive just taken in 3 hens. the owner said he had 5 but 2 died, and as he couldnt afford to treat these 3 he'd prefer they go to someone who could. anyhow ive looked them over, no mites, no lice, nice and well fed, no 'off' looking poo, the only 'symptom' that stands out is that all 3 have terribly pale combs, one worse than the other two. two have a pinkish pale comb, the 3rds comb is nearly a greyish blue colour. the guy couldnt give any specific detail on how the other 2 died, he said in the morning they were fine, in the evening they were dead in the run i have no idea how old they are, i forgot to ask, i think they are all sisters, sussex breed (white with black flecks round the neck?) any ideas?
