I got a group of Lavender Orpingtons from Hodges Farms. They were shipped on Monday and scheduled to arrive on Tuesday, however, did not arrive until Wednesday morning. Three were DOA and one died shortly after I got them settled. The rest seem to be doing fine except for one that is very listless and already seems smaller than the others. It can stand, is eating a bit and drinking, but doesn't move around much, just sits, and is very inactive. When I pick it up, there seems to be no weight to it whatsoever. Should I be worried? Is there anything I can do for it, or do I just wait it out and see how it does?
