I have a 4 day old chick. Noticed last night it wasn't as active as the others. Was picking at food but found it's crop almost empty. I moved it into another brooder box with two buddies. I ground up the starter/grower food more just in case. Put electrolytes/vitamins in the water. Thought maybe it's getting crowded out, not getting it's share. Just now I noticed that it's lower abdomen, really more the area below the vent, it enlarged. I wonder if it's having trouble absorbing the yolk. It has poop under it's vent so it's pooping. What can I do? I will feed it with a syringe just to keep it going....maybe needs more time. Any suggestions? Any thoughts on what's going on? Thanks!
