My two ducklings are about 2 moths old give or take. I just turned their heating lamp off today because I've noticed them panting. They are still in my house with me and are often running a muck lol. We keep it about 73° in the house and they are still panting and their little feet are hot as firecrackers! Still acting like their usual happy mischievous little selves lol. Not too extremely worried but would still like to know. To make sure they are OK.
