I ordered these chicks from Purely Poultry this year. Their website states they are a new hybrid developed in Wisconsin, that I supposed to be a good brown egg layer. Looks like we are some of the first to have these chickens.
My experience so far is good. I ordered 10 of these chicks. I got 11 live chicks in the order. To date 2 have died. One was my fault as I moved the chicks to the garage, I didn't get the heater turned on quickly enough and one was smothered as the chicks tried to stay warm. The other chick died of an unknown cause to me. It's feet turned dark, it stopped eating and drinking and died within hours.
The remaining chicks are three weeks old and are thriving. They are inquisitive as each time I walk by they stop and look up at me. My Great Dane loves them and mothers them.
I will post more as they mature and get out to the yard where I plot free range them.
