Hi! We noticed our year old runner made a strange noise yesterday when she quacked- we kept a close eye on her yesterday and noticed she was resting a great deal and every now and again began panting. This behaviour seemed to stop after a long drink and she seemed ‘normal’ again although no quacking. We let them out this morning and she doesn’t seem herself still and rather than eating like usual she just went to lay on the lawn and the strange quack was back, we have only been getting a single egg for the past few weeks so not sure which girl is laying or whether they both are and just not an egg each day! The other two (one male and one female) seem absolutely fine. HELP! ANY ADVICE WOULD BE APPRECIATED!! I’ve scanned the internet for the last two days and can’t seem to find any possible reasons!
