Roosters cone has flopped over very quickly is he sick?

[Farmer Peggy]

I have a two year old leg horn rooster and he had a great straight up big cone . Within a matter of 1 1/2 weeks it has curled and flopped over. Is there something wrong with him? Is this normal to happen so quickly? Any help would be greatly appreciated.
Thanks

You mean his comb? Could he be dehydrated?
