I have 16 ducks and 2 geese. In the morning I let them out of their predator-proof cage, and they walk down the hill to the pond to forage. In the evenings they walk up the hill for dinner. The hill they have to walk up is mostly gravel and dirt, and the past few days the temps. have been 106-109 F. I never really thought about their feet being burnt until I had to walk up the hill barefooted myself today. I had gotten my flip flops all muddy at the pond, so I decided to walk up barefoot. The ground was so hot I could barely make it up the hill. Once I did, my feet were bright red and were developing blisters. I feel really bad if they are getting their feet bunt. Do you think it's hurting them? If it is, I don't really know how I would prevent it, other then giving them shoes (just kidding). So thanks for the input!
