My females have all locked multiple times, went off feed for quite some time(almost 2 months), seek the cool side, and were lumpy and swollen. They shed on 1/16/2011, 1/21/2011, and 1/23/2011. Now they are all feeding like crazy again. Is this normal? and what does it mean? are they getting ready to lay, ovulate, or just building still? Need some info on whats up. Thanks
