I have 5-6 month old silkie hen that we are treating for gleet vent. However, she is having a very hard time pooping. She makes this noise every time she tries to go. Her gleet vent is slowly going down and getting better with treatment but she is still having issues pooping and to top it off, her crop is fairly firm even when empty. We have been doing Epsom salt through a syringe 3 times a day. I really don't know what else to try. I am thinking about doing vetRX if she has a respiratory infection.
