I have the tiniest chicks we have ever had! Our last batch of japanese are serama size so we are new to teeny tiny chicks. Most of the eggs I set I was fascinated by how small the eggs where so I just had to see if they would hatch and ...they did! all but two. Today I realized one had pasty butt so I cleaned it with a wet wipe and now the vent looks to be protruding. Like it's either constipated or has prolapse ??? I don't know what to do, I put it back in with the others for now. Then after I put some feed in (chick starter) the little piggies ate like they hadn't eaten today (they had only just then ran out of food) and a couple of them are acting like they are choking and I can see food in their throat. They keep stretching their neck and opening their mouth.... is their food to big? do I need to grind it up more for them? Thanks in advance!!
