We're worried about complaining neighbors too, so I hope that none are roosters.
I went to talk to the post office and left my number to call and I also left a note in my mailbox with the same info before their arrival.
I did everything that I read about with each chick as I pulled it out of the box. "Dip each beak in water and also I gave them food on a paper towel", etc. I also put paper towels all over the area where they were for the 1st few days. I did read somewhere that grinding up the chick starter with a little rolled oats would help them with pasty butt. (I had a few with that for the 1st week) I just ran the bathroom faucet with warm water to wash away the excess poop on their feathers and put a little olive oil around their vents. (These are all things I read about here on BYC and elsewhere on the web)
My chicks did seem to eat better when I ran the chick starter thru the food processor with a little oats and the poopy bottoms did clear up, so I guessed it worked.
I also have been scrambling an egg for them each day and feeding them that, they love it. (I never knew chicks could eat egg before) They seem to be doing very well. The whole family has been digging up worms and feeding them that too.
My Easter Eggers do look different from each other and we can tell them apart, they do resemble each other a lot though. I wish I ordered more of them.
Also, I add 1 TBSP of ACV to a gallon jug of water that I use to refill their water. I swore that I would never bring them inside and would keep them in the coup, but of course I failed and they are in a large set of boxes in the basement. It got so cold here that I felt sorry for them.
I am in no way an expert on this, I've just been reading a lot.
