Hi everyone, I am a new member but have been using this site for over 8 months. (thank you for all the info!) We currently have 6 chickens and we just purchased another 6 ready to lay chickens from a hatchery. 2 of the 6 hatchery birds appear down in energy, and they keep closing their eyes as if they are going to sleep or are in pain. I have check the vents for lice etc. and there appears to be nothing an their poop looks normal. The 2 birds are eating and drinking The hatchery said they were part of a flock of 5000 birds and now they are only 6 and the temperature is -15C. I have a heat lamp but I do not think it's doing much for them. Could it be worms or the sudden drop in temperature? Wondering if I should 1. just give it some time as it might be shock and the cold 2. deworm or 3. start antibiotics Any advice is greatly appreciated.
