Hi! I received my chickens - they are currently 72 days old (my 17 oldest - my 'babies' are only 23 days old - LOL). I had some substitutions - both of my Black Stars and 1 of my Silver Wyandotte's. I have figured everything out but one...I think she's an Australorp as she's looking more & more like my other, but she's 'behind' on the feather growth, etc. This was her a week or so ago. This goofy one in front is her now at 72 days. She has the blueish legs my other Australorp, as well as the green sheen on her black back feathers (which thankfully have come in now!). Like I said, I believe she's an Australorp, but my hubby isn't convinced. All my chickens but three came from MyPetChicken...so there are only a couple things she can be...and she doesn't look like a Jersey Giant! LOL! Any thoughts?
