Hey guys in need some advice ,there was an accident with my duck 3 weeks ago ,may cat jumped down while she was sleeping and landed on the right side of her head ,she had some bleeding from her nares and her one sinus cavity was swollen the size of a pea ,however she was fine and the next day her cheek swelling went down (im assuming it was blood in there ) she back to normal, eating,drinking,playing,sassy as ever lol laying her eggs daily ,she almost 3 year old khaki, however when ever she takes a bath that same sinus cavity would fill with water but always go back down by the end of the night ,now mon and Tuesday she didn't go in the pool it was raining hard so yesterday around 4pm and again at 5 pm she took a bath In her pool and her sinus filled up with water again but this time didn't go down at night it's morning now and it's still a little puffy , is there anything I can do to get the water out ? I don't want the water to stay in there and harbor bacteria and turn into infection
