I'm new to chickens. I received mine, 34 total, on Monday and have lost 4! There was just something not quite right when I removed them from the shipping container so I kept them separate from the others. One by one they have passed. Pine shavings are changed daily, fresh water 2x daily, chick starter, temp ok. The only thing I know that I have done wrong is lack of air circulation, but now that I know I have corrected. Surely this can't be the cause? McM did not seem concerned when I called them regarding losses. They shipped Sat morn and I did not receive til Mon morn. No food/water all this time? Perhaps this plus the stress of travel? One was a cuckoo maran and the other three were golden polish. This is breaking my heart! Please advise.
