I guess I spoke too soon. Yesterday we realized we had a silkie with a dirty butt and we saw her have some runny white/yellow poop. We cleaned her up today and my husband said her abdomen felt swollen and firm, not normal. He compared to our other silkie. Also our third chicken from before, the buff orpington, seems to have a bit of vent gleet again. Several of our chickens, including the buff orpington and one of the silkies (not sure if it's the sick one) have started laying down randomly out in the yard during the day. We checked their feet, haven't seen anything wrong with them. So it has seemed like something is going on with them for awhile, but no idea what. Also they have all stopped laying for the past week or two except for two of them.
So frustrated and discouraged, just don't know what can be hitting all of them. We're planning to corid the whole flock again, not sure what else to do. We're expecting a baby (human, lol) any moment now, so the effort we can put into treatment is kind of limited right now. We're planning to check the silkie's crop in the morning. My husband didn't like the way it felt tonight but I'm not sure you can really judge anything late in the day.
Any other ideas on what this could be??
