I have a serama cockerel 5 months old and when I went to get him this morning I immediately noticed his comb is very pale with a blue/purple hue it is uaually a really rich crimson he is kept in a dog carrier under the stairs at night but this has been his routine from getting him about 5 weeks ago he doesnt seem his usual cheery self what could it be and what should I do for him,I understand about cyanose,lack of oxygen etc but cant fit this in with his regime ANYBODY have any ideas,could it be diet etc.etc.etc.
