I cracked open a egg and found what looked like a parasite it was about half inch long. I noticed my chicken poo was changing color. it is pudding textured and a butterscotch color. i noticed my rooster also has lost alot of weight. i have more than one chicken coop. in the other one im starting to see the same signs. only i seen black poo once in there. now the poo is becoming watery. any kind of info would be appreciated.
