So I have 6 eggs from a friend's flock in lockdown.. Inc says day 1.. so anytime now I should get pipping.. we have no idea what hen may have lay them as he has around 40 laying hens atm, however, hen options are RIR, saphire gem, what looks to be speckled Sussex, Jersey Giant and a few other types probably ly mixed.. dad's he has 17 roos roaming his yard.. he put 2 roos in with his ladies and I was surprised to find that 7 of the 8 eggs he gave me were fertile. One was a quitter. I have barely a clue what any of his roos breeds are. Assuming they are all mixed breeds except for a Jersey Giant he got last summer and I believe he was one of the roos. Other roo was def a mix.
Question: I am really wanted a SS. Will the SS gene be dominant or will the mixed breeds wash it out to a mix of speckles and something else? I am so beginner on genetics and honestly having a hard time grasping it so any help is appreciated
