Hi everyone...I have a very odd chicken. Ever since she has been fully grown, she has had a weird lump on her tummy...almost fluidy and hardish. Thats not quite the biggest problem...She is pooping out yellow..yoke substance..shes has done it before..like a month ago..I don't think she has been really doing it that often..but there is yellow stained on her tail feathers. Could this be an egg is stuck in her? or she is continuously breaking her eggs and pooping the yoke out? She also has a very purplish comb...all of her comb is a deep purple..she is eating fine and drinking...but she does sometimes distance herself away from the other 5 hens.. Please helpp me! Thank you...it would be very appriciated..I am very worried..and can't bare to lose her!!
