I think it is only one of my 7 hens who leaves consistently runny poo, but I can never seem to catch her in the act to figure it out. Most of the poo in the coop and run is normal consistency, but from when we got them as 8WO chicks, there has been someone with a problem. Is this something I should be concerned about? All 7 seem perfectly healthy otherwiseshiny feathers, combs starting to get bigger, same activity level in all. Their food has been changed twice, but that doesn't seem to make any difference.
