Hello all, I have 2 female Saxony ducks and 1 male and 1 female Cayuga duck, I live in Maine and we've already had our second snow...high during the day is around 44f and at night its usually 25-31f My ducks have been in the barn in their pens since November first with a heatlamp on 24/7 today I had to unplug their heat lamp for a few hours so I could plug the electric fence in to keep my cow in check. I just plugged their heatlamp back in (6pm EST) and unplugged it around 3pm, I went out to the barn when I plugged their lamp in to feed everyone and make sure everyone had water and noticed all my female ducks have these saggy pouches that hang down on their chest, the male duck does not have this and the females didn't have them earlier. I am not a duck expert and frankly wasnt even prepared to have ducks as I know nothing about them. Why do they have these pouches? I picked one up and felt it but theres nothing in it, its not gushy or hard, it just appears to be skin. Are they dehydrated or did they just get cold or is this part of their egg laying process??? (My cayuga once had this pouch and 2 days later I had my first egg) Any advice would be appreciated...I'm quite worried about them
