So has anyone had luck with crossing heritage with broad breasted? If so, what heritage variety and how was fertility/ hatch/ growth rates? I have 2 BBB hens I kept from last year and I put them in with my Royal Palms,1 tom 3 hens. The goal being to have a larger meat bird with slower growth and less health issues. So far its been hard to keep the RP and BBB eggs separate to track fertility rates. Out of the 32 that have hatched so far, 5 have been crosses. With the RP having well over 90% fertility and hatch rate. I'm assuming the duds were from the BBB which would put them around 35%. Even more interesting is the crosses have 3 color variants, a light sandy brown, a white and black, and the standard darker bronze. I am very curious as to how these will pattern out. It would be really cool if they're sex linked. Basically looking for any info on this as I haven't found any. Also any theories on why I would be getting 3 colors?
