So sorry...I would NOT put heavy things on his hides to hold them down...they may slide off onto him & hurt him.
It does sort of look like a seizure to me too, vet trip may be a good idea. Also you might ask the vet if you should bring any bird droppings to test...it's possible that
your bird is carrying something that could make your snake sick, & since he's in close contact (same room etc) that might be worth looking into rather than a "shot in
the dark treatment".
Feel better soon, little Crowley.![]()
