Hi I have just put in my coop 4 new hens but I’m not sure if one is sick. They all seemed ok for a few days then one of the hens seems to have her lighter feathers spiked up and seems abit fluffed up, she is eating and drinking ok I think but seems abit lethargic. I have not seen any loose poops or any blood in there as I am worried about coccidiosis with the feathers looking rough. I have seen pictures online and some birds do seem to have spikey feathers but it does not look right to me. Anybody else have experience of this as help would be much appreciated.
