Don't know if you're still struggling with feeding your neonates but don't feel like you're the only one with this problem. Chondros are known problem feeders as neonates. Getting them started is a learned art and one best taught in person by someone with experience. Thankfully I had someone show me a couple of months into my first clutch and my second clutch was MUCH easier to start. I actually posted a couple of feeding videos on my web site for those with stubborn chondro neonates. Take a look at it and see if you find it helpful. I find that most people aren't been aggressive enough or spending enough time on each neonate. Also, I try stubborn feeders every 3-4 days. I start assist feeding pinky heads within the first month if they're aren't taking pinkies on their own.
