Thank you, I'll try that. So you don't think its fowl pox?
It doesn't look like fowl pox at this stage , but if it becomes crusty then it's quite possible. Anti fungal creams will have no effect on pox as it is viral not fungal. I would dab the lesions with a bit of betadine and keep them quarantined for 3-4 weeks.
Do you know whether or not they have been vaccinated and if so , for what ?
