These are our first 4 chickens. We got them 5 weeks ago and I believe they are about 20-22 weeks old now. We love them so far, even our 2 year old labradoodle. 3 of them look just like the website and are gorgeous, but one of the Australorps is a stumpy little thing. Her crop area seems a lot larger compared to her body than the others. She's the sweetest of the group so I really don't mind as long as she's healthy. Picking her up she seems lighter than the others but has just as much energy and curiosity. Haven't noticed any diarrheal, or anything and she eats and drinks about the same as the others. Is there any health concern I should be worried about or is she just a little short and rotund? Thanks for your help.
