Got a hen (barred plymouth rock) that just lays in the nest box. comb is pale pale with white. I dont see any green droppings but someone may have had watery, as in clear watery. I noticed a wet spot under one of the rosts.. Didnt see anything on the roof where it might have been a leak with all the rain we just had... temps have been < 32 but I've had the heat lamp in there and going. yesterday this hen was standing on 1 leg under the ladder that goes into the nestbox.. today she is curled up and not moving. I know she is breathing but thats about it. other 3 hens showing no signs of anything. good looking combs, eating well, going crazy in the run etc. no bad looking droppings anywhere I can see.
