We have six lovely cuckoo maran chicks - all doing well. One of the hen chicks seems to be a manx. She has no tail feathers (pic). I have observed closely and I can't see that she is being bullied by any of the other hens. There are no bald patches where her tail feathers should be. She seems a bright and interactive member of the gang.
Any suggestions? Is it just normal variation?
Also - when I was watching her, I noticed that she passed a pale, runny rather frothy poo (pic). There didn't appear to be any blood in it or any obvious worms. They were all wormed with Flubenvet the week before last. She is having a mixture of layers and growers pellets. The growers have got coccidiostat in them.
Any diagnosis/suggestions?
Thanks
