I have a few pullets (3 months old) that are in quarantine due to some respiratory issues/foamy eye. I have been treating with Tylan 50 for the last couple of days (. 5cc 2xday) I went to check on them and noticed this poop which at first I thought was blood, but upon closer inspection I'm thinking worm. I planned on worming them with Valbazen, but was going to wait until they were no longer on the Tylan. Wondering what kind of worm it is, and if I should wait, or go ahead and treat with Valbazen now.
