I did treat my coop. it looks like chest feathers are coming back in and I'm getting back to 5 eggs again. i went down to 4 eggs than 3 eggs. I was new to chickens i bought these at a swap. they were not in the best shape. please keep me posted. I bought some girls from fleet farm they are now almost 3 months and I fear they may contracted respiratory, some of thier voices are raspy so I just ordered tiagaurd from Amazon. I'm getting overwhelmed

about to cull all in a month. I work 50 hours a week and it's alot of work. share any info you have and good luck!
