These are the 6 new guineas I picked up on 9/16. Lady said they were about 10 weeks and I thought they looked at least 12, unless they can grow faster. She said they were about 7 weeks younger than her chickens that she got in May. There is one male & 5 females in the group of six. Their wattles are totally not "girl" looking, but the one in the middle picture was butt cracking at the time and so is the one on the right of the first picture. I surely couldn't tell they are girls from the wattles & size. Can anyone tell me how old you think they are? Full grown is all I see. I may be able to call the place where she got them and see what dates they got guineas in. This picture would make them 11 weeks by her count and my guess would put them at least 13 weeks. Can guineas grow too fast? Thanks.
