I just got back from Cubscout camp with mu son and 13 of our hens have really swollen crops. My husband was taking care of them. He fed them the same feed and kept them on the same schedule. The only difference is he said that twice they were out of water by the tim ehe got home. It's never been a problem before b/c I have always been home (we are buying more waterers tommorrow). Is that what has caused this? THeir crops are tight. They had also ran out of grit while I was away. I out out more grit and tons of water. Does anyone know what I should do now? THanks for your help.
