I may be able to help you. Key words may be. Two years back I crossed a 8.5lbs Delawares cockerel over several breeds including Rhode Island Red and New Hampshire Reds. Delawares carry the barred gene. I keep only one mature male on the farm at a time and currently have a 7 month old White laced Red Cornish cockerel. So any hatching eggs I have would be half WLR Cornish. I also have a 16month old hen "DELxNHR" that I would sell hatching eggs from, outright sell her, or trade away. If your interested in hybrids you can buy hatching eggs from the following.
Current Flock:
1 WLR Cornish-Cockerel

Hens:
2 NHR

2 Buckeyes

1 SLW
2 Delawares x Buff Orpington (my best layers yet)

All my hens are laying except the mommy.
