pretty sure...the aussies' feet bottoms are yellow and the JG's feet bottoms are pink. I got the aussies from a friend who said the older one had started to lay; the younger one was at least 6 mths old - I could tell them apart because of the difference in size & the older one was fully feather out & looked like an adult - I can't distinguish between the 2 now. The JG I got with a BSL & a PR...they were all about the same size...the BSL & PR have been regularly laying for about 1 month now. I've read that that the JG is slower to mature.
I've had all 3 for at least 4-5mths. For some reason the BSL, PR, EE and Andalusian all share the same nest, but there are other nests in the coup un-used so there is room for the aussies & JG. I'm just wondering if I'm not doing something right...the older aussie had been more free ranging in her former home and she continued to do so here although my other hens stayed in their chickyard - the aussie decided she didn't like being alone and she joined the flock. They are lovely hens..
