it's a cornish x, overall healthy now at 7 week. it's dirking and eating well and was totally fine till now but suddenly it became very weak a few hours ago. it's poop looks fine there are no sings of respiratory diseases. it is just breathing very heavily usually doesn't pant , but pants when stressed. i don't have a mother hen and it's the only baby chick i have. is there anything wrong with the panting? should i do something about it? any medications? plz help
