Well...I say if you set that many eggs from those Blue Cuckoos...going that route of keeping only those from the darkest eggs and with leg feathering, it will certainly launch you ahead...
how many SLW eggs did you get this time? I hope they hatch better for you this time.
I haven't decided when I will set eggs again, I've got so much going on and not feeling good, so I'm not in a rush like I have been the last two years. Plus, I'd like to see what these new wee (or not so wee) chicks develop into over the next three or four weeks. I want to try to be more concentrated in my focus with hatching, going group by group. I'm hoping it will keep me sane this year
I don't know if any will be feathered from the dark eggs. I only have one pullet with feathered legs, she has also plucked all the vent feathers of the other two girls... I think it is nerves since she is in a cage and was in a huge pen before. I hope you are right. I think I set another 12 today.
20 SLW eggs, she got hers from the same place so I am hoping they will look just as good.

My goal is to only hatch one breed at a time for me too. Keeps things easier, I hope. This was just an odd thing to have all these eggs hit me at the same time.... I hope I can handle it.
