Kelsie X2. Looks like a ruptured or unabsorbed yolk sac. I would follow the link that Kelsie has provided to the emergency section here on BYC for more help. I the mean time, he will need more heat than the others. Get him in his own small brooder with heat around 98 to 100 degrees. This may help him reabsorb the sac, but many times babies like this don't survive.
Good luck with the little guy and welcome to our flock!
