All three look to have good leg feathering, the middle pullet is pretty nice! I also raise LFS. I have a Black rooster and 2 lavender blue pullets and one buff pullet. Now for the not so good parts, the Splash pullet doesn't appear to have much color, it may come as she ages. The rooster is'nt as round and fluffy as I like to see. Just my opinion. I always prefer very round LF Cochin rooster, Like his tail doesn't Round off like I like to see. But, he is nice as well. I think when he covers the two pullets, it will create nice chicks. Hopefully throwing a splash, blue, and black. I think if him and the Splash pullet have chicks that are splash colored, it might add more color to them. I think these guys will be a good start for you congrats! :)
Im sure you've already figured this out but I'm still going to say it lol. Try to aviod wire on the bottom of your pens at all costs, it damages feathers. I like to keep them on a loose fluffy dirt flooring or wood shavings. I have a hard time keeping white feathered feet clean, but usually some Dawn soap works,
If you want I will post pictures of my birds soon. I hope this helps some. Have a great day!
