I have a hen who had fly strike about three weeks ago. We solved her maggot problem but she hasn't laid since then so I checked her vent again today and it had a black crusted over scab looking thing. there were a few mites around it but nowhere else on her and I don't see any in the other girls either. I soaked her and peeled it off, doesn't seem to be anything going on underneath. wth. anyone have any idea what is going on with this chicken?!? oh, I googled gleet and it doesnt look like that.
