Our three week old is not pooping right. She'll usually do one normal poop, 3 or 4 water poops then a water poop with bits on normal poop in. What I mean by water poop is literally water. Perfectly clear, doesn't smell, it's like the water's gone straight through her. She seems to be in perfect health otherwise. It isn't hot, she's not lethargic and it's been going on for about 2 weeks. She drinks a lot too. Like drinks until her crop is so full that it swings as she walks. Any help? Thank you.
