Hi everyone, I am new and I need your help! Let me first tell you that I don't own any chickens, but the people I work for have 2! they are two beautiful amerucanas who I just love! Their owners don't take good care of them, they just want them for the eggs and because they look "cute" in their backyard when they have guests. In my spare time (which is almost none) I try to keep their cage, food and water clean... unfortunately it is not enough as I just found out that one of them has canker! and I believe it started about 2-3 months ago! They went through a hard molt so they lost a lot of weight and stopped laying eggs but one of them has gone back to normal, that's when I started to suspect there was something wrong with the other one. She is very, very skinny and spends most of her time resting and looks like she is cold. Today I picked her up and took her to a sunny spot and she fell asleep in my arms. At first I thought she was anemic so I went to boil some eggs (which she loves), when she saw them she immediately went to the bowl to eat and that's when I noticed she had trouble "swallowing", she started doing some strange movements with her neck. She had done this before (about 1 month ago) but I thought it was because the food was cold.. anyway, after she ate the eggs today I decided to check inside her beak and was shocked to see the yellowish-cheesy growths inside her throat! I am extremely sad and mad at myself for not noticing earlier!! I really hope I can still do something for her! but for that I need your help! I would like to know what is the best and most effective treatment for it? I've read several posts that suggests using Fishzole (metronidazole) 250mg for 5-7 days. Now the problem is I only see her 3 days a week so I cannot give this treatment! so I was wondering if anyone knows if there is another medication that will work faster? or does anyone know if canker medication formulated for pigeons/raptors work for chickens too? I ask this because there is a pigeon/raptor medication called "meditrich" (it's also metronidazole but 100mg) and it is single dose only!! I know Fishzole is used for pigeons and chickens, so do you guys think this other stuff could work on her? as I mention before, she has had this for a while (and I don't see her too much) so I want something that will work fast! Please let me know what you think or if you have any other suggestions too! Thank you so much!!
