I'm sure they aren't SLW. I have 3 of those! To update everyone: they are getting BIG. They have grown faster than any of my other girls and I'm starting to suspect 2 of the 3 are roos! They were hatched Aug 31 and they are bigger than my SLW from spring. My husband calls them the "troglobabies" because they hang out inside the coop most of the time- I suspect that might be part of the reason why they are so big since they never stray far from the feeder!! I can't wait to show them off in pictures.
