I understand I should have isolated. I have rolled the dice 2 times now bringing in birds from other peoples flocks and prayed my girls would not get something nasty. I have to find a way to isolate, I have only one coop. It is hard to house 10 full grown hens for 3 weeks before I bring them into my flock.
I am going to work on this.
For the time being, regarding this hen, how do I treat the infection? Can I smear neosporin into the cavity, or is the fact that it is inside her mouth a problem?
I can go to the feed store in the morning and see if I can get some injectable tylan 50.
