It may be normal but my redfoots seem to be eating ALOT more now that they are outside on a normal basis,Can I overfeed them they seem to want to eat every day while earlier in the year every other day seem to keep them happy.
Summer seems to increase the appetite of my RFs too. I believe this because of more natural environment (varying temps, natural light, and wider food choices). Mine will eat twice day on what I offer and forage the rest of the time. Actually I see this with all the species I keep and when they have be brought indoors the weight, appearance , and general health is excellent .
If your care is fine then it will make them healthier, however do be aware that quick pyramiding can happen if feeding a lot with bad care-humidity, temps, diet, lighting etc.
