So I’m on my first go with chicks. I started with 4 and today it looks like one is not going to make it. Not sure what happened this morning I feed and changed water and they all looked good. Come home from work and one is just laying down. It is clearly not going to make it. I have had them 2 weeks now and the temp is at 89. Is there something I should be looking for or was it just a weak chick? Not sure what to do if anything?
