Thanks. I really don't know exactly, Linda. This is the first one that I knew for certain that I had removed the oviduct. I have 3 more Marans pullets that I am doing tomorrow along with caponizing another little roo. I have some Bresse pullets that are about 4 weeks younger than these, so I think I am going to try a couple of them within the next week to get an idea about the best time for them as well. That would put them about 6 weeks before POL. I suspect that may be the best time......but it's just a guess.
The Marans generally are older than the Bresse at POL, so I figure they will be poulardized at an older age than the Bresse.
Good to know. Thanks I'm so excited for you.
