Backstory:
We recently bought a second batch of quail eggs from a new breeder intending to breed them with our first batch of healthy quails. A week after they hatched we started noticing some abnormalities. One had its wingtips facing outwards(now seems normal), some running backwards, one wasn't growing bigger and one, we believe, had an eyelid that had grown over. Now it's a bit past two weeks we've seperated the ones that look severely ill from the chicks that look fine and we don't know whether this was caused by inbreeding, diseases etc. We also started noticing some with swollen chins and weird sneezes like they were having breathing problems. The chick that wasn't growing bigger is now half the size of the chicks that seem fine. We haven't noticed them fighting each other as well.
We doubt it would've been temperature/humidity issues since we calibrated it from the start and everything was stable all throughout compared to our first batch (which still ended up fine when we had our power cut for 5hrs straight!). Should also note that we discovered two eggs that were cracked through (but didn't find anything that had leaked out) a week after incubation started when I was candling them.
Chick with the swollen chin
Other sick ones
Chick with the sealed eyelid.
Small chick compared to the other sick ones.
Here are the chicks which seemed fine.
Thank you for any replies.
