My two baby chicks were not eating their starter feed but we're drinking plenty of water and running around happily. I tried 'pecking' at their feed but they showed no interest. So one evening I added very small pieces of strawberry tossed in with their feed so they could get the taste for the feed. The next morning every last bit of strawberries and feed were gone, they ate every last bit. I was so happy until that afternoon one of them had died. He was the weaker of the two so i figured the strawberries were a coincidence. So last night I gave the other chick a small amount of strawberries and now this morning he is laying down and faintly chirping. I don't think he will make it much longer. I'm so sad, did I kill my babies?? The first to die was 5 days old and the other is 7 days old. We're they too young for fruit or were the strawberries a coincidence? Also I didn't provide any extra grit because the strawberries were mixed in with their starter feed. Should I have still provided extra?? Where did I go wrong, please help! Also they were in a huge tote with a heat lamp, pine shavings, plenty of fresh water, starter feed and also a stuffed animal to keep them company so I don't think their environment was an issue.
