I have a ?: My Nankins are doing something I've never seen them do before, they keep swallowing or trying to swallow. Sometimes they look like they are shuddering from trying so hard to swallow. They do this repeatedly. I normally only notice it in the evenings, I think 1 may have done it earlier in the day yesterday after I feed them some clover (no long stems). It started out with 1 doing it, she has stopped but now another hen and both roos are doing it. I just noticed them doing it this evening. The hen looks puffed up and tired, the roos seem fine other than the repeated swallowing gesture. They all ate and drank fine when I fed them dinner. I noticed that they had spilt their water when I went out to feed them, they weren't out long as the ground was still wet from them spilling it. I haven't felt their crops yet as the 1st 1's to do this never did it again after the first time and I just noticed the 2 roos and the 1 hen doing it this evening. I'll check their crops in the morning though. Are they just adjusting their crops or is it possibly an impaction or something else?
