My 2 Lamancha doelings from 2 different farms. The little white one is (supposedly) 5 months old and the bigger one is 4 months old. The bigger one is 1/4 Nubian, but I dont think this accounts for the incredible size difference. I havent weighed the big one I assume she weighs 50+ pounds, but the little one only weighs 25# she has gained only 5# in the past month. So Im thinking that the little one is a mini goat and Ive been lied to... Unfortunately the pictures dont do justice to the size difference. The big doeling is new and wont come near me yet.
