red or green? does it matter?

also is the skin okay for them? better without?

i have given red apples, just cuz they tend to be sweeter... but i leave the skin on... they eat the entire inside and leave the skin, which means more work for me when cleaning, so i guess it would be up to u

Leave the skin. Most of the vitamins are right under the skin, and the gliders will eat all of the apple up to that point. A little more cleanup, but you've already got a mess, right?

I always peel the skin but VERY close. I don't CHOP it off.... just gently peel a thin piece.. most of the time you can even see some of the red from the skin on the 'meat' of the apple.. that's how close I peel it.

After chopping the apple i diced it and mixed it with papaya so far he seems to like it and seems to have a good ratio.
