I am wanting to start a project on making large fowl partridge(and/or pencilled) using bantams in that colour mated with Lf gold laced. I have two large GL hens from unrelated lines, one with bad markings that are perfect for this project. And a trio of partridge bantams and some silver hens. I am wondering if a bantam roo could successfully mate with a large hen? even if the fertility rate is low I do not mind, I would rather not AI, how hard is it? Then would I imbreed the F1s? From what I have read I am thinking that this would result in the bantams dying in their shells as they can not absorb a large yolk? if i want to keep silver in there to segregate later into a silver penciled line, then I need to use a silver rooster, (breed or buy one) or could I use a large roo over my penciled bantams? (I am aware that it could be mean penning them together but i would think that controlled matings would be ok) Which mating produces largest F1s?
