I had a similar issue and I picked up furosemide from Walmart. I told the pharmacist what the issue was and he was really good about it. Asked how much the hen weighed and then said to cut the pill into 5 pieces and crush each piece individually and mix with whatever you want to give her. ie: yogurt. Not too much yogurt as you want to get this piece of pill into her with a syringe or if she’s still eating, that way. It worked for my chicken but she it comes back now and again and she lets me know by gaping. It wasn’t gape worm. It’s jyst how we communicate. I have smart birds. Lol
