My cockatiel was doing fine when the fireworks started tonight and I let him go to sleep. When I came back to check on him his right wing had some blood on it. I tried toweling him and also attempted to put styptic powder on him and then he ran back in his cage. I cant see any fresh blood and hes hopping around his cage and playing with toys but hes shaking and I dont know if I should just let him go back to sleep. Hes also preening a bit and chirped a little. Theres only full wing feathers at the bottom of the cage. I'd take him to a vet but all the avian vets are closed. Any advice?
