My male Coturnix is a pet that lives outdoors in Missouri with his hens. The pen is like a 5-star hotel - protected from wind, cardboard floor with pine needles, little nest boxes. This male is about 2 years old, had some problems in the past with his eyes, and was treated by a Veterinarian. He favors his poultry heating pad (like a Thermo-peep heating pad), which he stands and lays on in the Winter for warmth. I trust my heat source and do not think that it burned his feet...I believe he would just move off if it got too warm. Which, again I don't think it does - I routinely check. I just don't understand how the pen could have damaged his feet, since 98% of the floor is covered with cardboard and pine needles. Thoughts on what is happening with the bottom of his feet? I can check the females but as far as I know, their feet are okay.
