Hi, we are relatively new to having chickens. We have 3 girls that are 2.5 yo and weve raised from chicks. They are Isa Brown cross and Australorp cross. They are gorgeous girls but one of the browns has stopped laying so we invested in 3 more chicks. Two are from the local produce shop and we have no idea what they are. The black one looks like an Australorp cross but the brown speckled one I am suspecting has some Faverolle in it. She is the biggest and is probably 7 - 8 weeks. Any ideas on gender and breed. Any thought s would be appreciated. We're in Australia.
