My new chick "Mork" has a rapid heart beat. Not really sure about his breathing but that little heart of his is beating a mile a minute. He seems tired but eats & drinks. The other thing is his lower abdomen. He had putty booty so I cleaned him up. Now his belly is a bit swollen & he has plucked off all the feathers. It looks bad. Thinking it to be constipation as I watched him for at least a half hour & he never pooped, I gave him a little vegetable oil. But even before pasty butt, he has always had a rapid heart beat. Any ideas what causes that? I'm worried I will loose him.
