This is bony my partridge cochin and blue laced red wyandotte mix we got off of face book she said they were about 3 weeks but she had multiple hatches going on so... I'm thinking around 5 or 6 weeks.its fully feathered and has a hen looking face like you just know its a girl but her tail feathers are curved down which i understand can change once they get their adult feathers. Her supposive saddle feathers are pointed a little. Her comb is not that red and not much waddle devolupment compared to her half brother Clyde whoe is a white top black polish and blue laced red wyandotte mix. thanks...just wanted a second opinion One with the small puff is clyde the rooster for comparisin see the red red red comb even though its blurry. Others are of bony.
