We keep losing some of our chicks and we can't figure why. We were wondering if it was due to them eating the berries of the polk salad next to our yard, since some have been covered in the purple juice. I know after a certain amount of time they are considered poisonous but birds should be able to eat it still. I'm not sure if it's the polk salad or not I was just wandering if anyone knew. The last one was wheezing before he died but I don't think he was sick, as the rest of our flock is fine. Just the chicks who are about 6 weeks old are dieing. We wondered if the others were beating them up, but the hen that has chicks that are about 2 weeks old, her babies are fine. Granted they do have mom to protect them and she does a bang up job of it too. She wont let the big ones get close to her babies. Like I said I really don't think they are sick cause they were fine until my husband let them out of the chick pen and NONE of our chickens have EVER been sick. And we've had our poultry for almost 2 years now. Never had a sick one before. Any help would be appreciated.
