Hoping someone can help.Chicks are 2 weeks old and today i noticed this on one of them.Cant make out if its an injury or a problem.Chicks are in with rest of the flock to roost but spend all the day with mum in an adjoining area seperated by mesh.From what ive seen, the rest of the flock including daddy roo tolerate them well and ive seen no mallicious behavior. Thanks in advance
