I noticed this in the run this morning. None of my chickens are acting ill. It has been insanely hot here the last couple of weeks and today is the first relief we have had. Chickens are all up and moving like normal. No one is puffed up or lethargic. I currently don't have anything on hand, but the feed store is only a 10 minute drive. Should I be worried and do I need to go get something? Update: I just spent sometime watching the chickens poo and I was able to see some tiny roundworms moving in one chickens poo! So that is probably my problem. Since most of my chickens haven't been wormed since they were 10-12 weeks old should I hit them with Wazine first?
