My chick is roughly two and a half months old and about a week ago, we noticed some black spots on her comb, and now it is flopping in front of her eye, though it doesn't seem to be progressing any further for now.
Welcome to BYC - sorry for the circumstances. Do an on site search on fowl pox and see it that looks like the problem. The bird may very well be a cockerel.
It could be fowl pox, or dried blood from another chicken pecking on the comb or even frostbite if it is humid and well below freezing where you are. Where is that?
You probably know that Andalusians are a Mediterranean breed and as such, pullets'/hens' combs are supposed to flop over. Only rooster combs are supposed to be erect.
