Yesterday morning had a doe fawn born to a two year old, first time momma. The momma looked pregnant, but did not look like she was ready to fawn. Momma was natural bred and is one I bottle fed, so she is very tame. The fawn was just over 4 pounds and developed completely except her eyes are closed except for a little bit in the inside corner of each eye. What would cause that? Is that a premature birth? Will the eyes open at some point? We picked her up to bottle feed as she is too small to reach the udder. We know she nursed at birth b/c we saw her nursing. Any ideas?! Thanks!
