To narrow down what could be a huge topic, let me say that a hybrid will not "breed true". If you had a golden sexlink rooster, and bred to a golden sexlink hen, you wouldn't get offspring that could be sexed at hatching time.
IF you had a rhode Island White hen, and a Rhode Island White rooster---all their chicks would be golden sexlinks...for all the generations of their chicks that you hatched. So as long as the parent stock lived, you could hatch out hybrids.
One of the reasons that they outlay the pure breeds is that the combination produces hybrid vigor....and they perform better statistically than both parent breeds would separately.
Henderson's chicken chart will give you laying rates, but they don't include hybrids. You may check the forum here----look for the type of hybrid.
I had a golden sexlink hen -- she daily produced an extra large or jumbo egg....she was amazing. I must add that her 246-egg production of non-stop daily laying began in April when I got her. I don't know how many she laid in the first few months of that year.

whoops I just read this again and I meant to say Rhode Island Red rooster...... duh. other way as I wrote above would be pure bred Rhode Island White....hopefully you caught that one. :O)
