My chickens wattles and combs look scabby and bumpy what could this be?

Scabs on wattles and combs could just mean that your chicken has damaged their comb somehow – perhaps by getting it caught on something sharp.  However, or it could be a sign of a condition called Fowl Pox of Favus (ringworm); we would advise to get your chicken to a veterinary professional for a full examination and diagnosis.
