I have one EE chick that isn't thriving as much as the others. All 7 of the others are much bigger than this one. Some of them seem to be almost three times its size. I have seen him/her eat and drink so I know it is not due to not being able to eat. I have had to separate it again from the others cause they basically run over & squash "him". He/she doesn't seem to be gaining much weight either. Is there something else I can feed in addition to the starter/grower to help it gain some weight and strength. I had added electrolyte and probiotic to the water at times. It had a prolapse about a week or so ago and we got that cleared up, but it is back to acting all weak and barely making it. I'm so afraid we may lose it.
