bottom was cracked a bit, when I cracked the egg open I noticed blood in the membrane part. honestly it kinda turned me off to breakfast so I just seperated it and ate the yolk. Why would there be blood? how can I make her shell stronger? The egg she laid for me yesterday has a good solid shell on it, todays was thin I feed them layena (same as previous owner). They are in and out of the coop from dawn till dusk (same with previous owner). I've had her 2 1/2 days now.
