Im sure some chitin in the diet is very natural indeed since most insects have it, it probably provides roughage/fibre, some proteins perhaps, but I dont see how it might be particularly good for skin as anything else in a natural balanced diet.
I dont share Brocks theory that chitin ingested is converted to chitin developement in the lizard that eats it.
I think I added my thoughts (got on my soapbox if you prefer) to the thread you mention Codi, but cant for the life of me remember what it was called, or even which
forum it was in, but ill try to find it.
Im curious about how many eggs per clutch and how many clutches per season an anole is capable of too, somebody here mentioned a plan to breed them and geckos for their vine snakes and I had the same thought, that sustaining an animal on them may be difficult for this reason, although with enough pairs, artificially induced to breed regardless the time of year, meeting the needs of a snake would be possible.
If you only fed an anole or gecko hatchling to your lizard when they did breed , aka a few times a season, this would probly come close to emulating how often a cham might catch one in nature.
Is this the thread Codi?
