Breeding Isa's to Isa's will I still get awesome layers?

[Spitman]

I love my Isa's what will happen if I mate my isa hens to a ISA Roo , will I still get awesome egg production? Or what if I mate her to my RIR will her egg traits carry to the next generation? Last if I mate her to her own offspring 1st generation isa hen RIR Roo , mate there offspring Roo back to her will her traits, egg laying and size pass on. Any help would be awesome. Thanks

Your results will probably be all over the board. The F2 generation is typically the most inconsistent, from what I've been told. Mate good layers to good layers (or roos from good layers) and you should get good layers, everything else could come out pretty jumbled.
