Quick question....

I have 4 BP's, 1 Boa Constrictor, and 1 Corn Snake, they all eat F/T rats no issues, except the Corn he's on F/T mice

Should I vary their diet by offering a F/T chick once a month or so? Any reason to do this?

Or is that asking for trouble and screwing up their diet, and making them fussy eaters?

Right now I've never had one refuse a meal don't want to mess that up.

Any reason to add any kind of vitamin or supplement to the food they eat now?

Just wondering before I place my next order for rats/mice.

Thanks for any input.
