Well after some more research before worming I just got the Safeguard yesterday I found out it is an infection called Vent Gleet so I am relieved it's not worms! So now I have to bathe most of my flock in warm Epsom salt water which I would prefer to the worm treatment so I looked at causes & moldy feed is one of them so I think I gave them some leftovers that were a bit moldy causing my problem.Thank you for your help & wish me luck!
