I have a ten month old black australorp hen who seems a little under the weather at the moment. She hasn't laid for two weeks, then about ten days ago her appetite dropped off and she started dropping feathers. Her poo is quite sparce and green (clearly from not eating much), and sometimes a bit runny/frothy. She's also preening a lot of the time and sitting down more than usual. Otherwise though, she's her same old self - flying up onto our picnic table (which for a hen as huge as she is must take some effort!), chasing the wild birds and still with a lovely red comb and wattles. She's also drinking fine. Is she just suffering and feeling miserable with this molt, or could she be ill?
