It looks like he has scabs on his face and comb? Has he been in a fight recently?
You might want to run a search on "wet pox" and "dry pox" to see if any of those symptoms match his. I know one of those diseases cause spots on the comb, but I can't remember which one.
Thats what I was thinking but he has not been that I know of and he dose not scratch a whole bunch so I dont think he has mites and not sure it would look like that.
That looks like fowl pox. My old flock had it once, and I'm sure my new pullets will get it eventually...So many mosquitos here...As long as its dry pox not 'wet' pox he should be okay. I would add alittle vitamins to all the waterers and make sure he is eating and drinking. If any of the sores are open you can put alittle neosporin on them so they don't get any worse. If it is fowl pox it will take about 2-3 weeks to fun its course and if your hens get it (it is contagious) they will stop laying while their bodies fight it off. I would look up some info in and make sure its not the 'wet' kind though.
Fowl pox is a viral disease spread by the bites of mosquitoes. The infection leads to warty nodules on the bare or non-feathered parts of the head and legs and sometimes lesions in the beak, nostrils and throat. It depends on location, but pox is referred to as either skin pox or 'wet' pox.
The most common outbreak is the skin form, showing warty-like eruptions. Pale lumps form yellow bumps which may enlarge and run together forming masses of yellow crusts. It takes about a week for these scabs to darken and fall off.
The 'wet' pox form shows up in the beak, nostrils and throat as cheesy masses which interfere with eating and breathing.
Treatment is of little value. Lesions normally heal within 4 weeks. In severe cases it may be necessary to remove scabs and treat with antiseptic washes. Adding water soluble vitamin tonic powder to the flocks water source will help them fight this off.
Warm salt water can be used to clean off nostrils and beaks. The addition of 1 tablespoon of cider vinegar to each gallon of water can help reduce mucus but must not be mixed with the vitamin tonic.
Prevention by reducing exposure to mosquitoes is the best defense. Screening sheds and coops and by dealing with mosquito habitats. Vaccination is effective and warranted. once you are aware that this is prevalent in your area. Consider this when adding to the flock in subsequent seasons.
From Another Source:
If you are considering breeding/raising birds, I strongly suggest that you breed for resistance. These are the birds that get sick and recover, are less sick than others, or don't get sick at all.
In some instance of poultry disease, it has been found that it IS possible to reduce the amount of out break on your property by doing this. It is much in the same way as some people get more sick than others.
Although you may not want to and it seems cruel, a still programme of culling and breeding, i.e. culling ANY bird that seems to get sick, will ultimately improve your coop (suggested for the serious breed/farmer but may not be approiate for hobbyists).
But the thing is i never saw any thing wrong with him as in showing warty-like eruptions,Pale lumps form yellow bumps. I have spent a little time with the chickens every day I sense i have got them I would have noticed them nasty things. I just noticed the scab looking things yesterday... Hmm
