Several of my BBS Orps. that are a wk. old have bulging crops. My splash is the worst. Is this normal or is it a problem? What do I do to fix it? They are only being fed chick starter and water. Their bedding is pine mulch which the 1 wk. old Delawares keep scratching all over into the water. Is there a possibility that the Orp. chicks are eating the mulch out of the water and it's getting stuck in their crops? I've waited so long to have these Orp. babies and I don't want anything to happen to them. I just want to sit and cry. Please help!
