Need advice on completely starting over with chickens

Hi there, I'm a brand new member of this group, after reading lots of posts over the past couple weeks I have decided to join and ask for advice. We had a devastating fire on our property last August in which all our outbuildings were burned to the ground, our chicken coop included. All of my chickens perished in this fire. We have spent the past 6 months doing demolition and clean-up, and we've recently started rebuilding. Our new coop will be finished in a couple of weeks, and I have chicks scheduled to arrive in April. I've had chickens for a long time, but my concern is that I've never had so many chicks at once before. I've had up to 8 chicks at a time, because we've always had some adults around at the same time. Since I'm having to start completely over, I've ordered 30 chicks. It's been a few years since I had any chicks, and usually we have hens to tend them. I'm a bit stressed thinking I might lose a few because there will be so many to tend. Are there any risks with raising this many chicks together? For the first two weeks they will likely be kept in the house downstairs inside a wooden box 4 feet square and about 18 inches high. I planned to use pine shavings for the substrate while they are in the house for easy cleaning until they can be moved out into the coop. Is there anything special I should arrange for them aside from the basics of a heat lamp, food and water? I feel kind of silly being so stressed about keeping a bunch of baby chicks alive, but I am concerned that the disease and mortality rates go up when you have higher numbers of chicks together.

 

Thank you for your replies. The fire was devastating, but we are blessed it wasn't more tragic. No other lives were lost, and the houses were saved, it really could have been so much worse. I ran through the flames to save one of my dogs, and I honestly tried to save the chickens too, but the fire was so huge and I couldn't get them out. They were pets to me just like any other, and they all had names and I loved them. It was so hard on me to know they suffered. And almost worse is the fact that for the last 6 months we have had to rely on store bought eggs, which in all honesty just taste terrible to me so I mostly just go without. I can't wait to have fresh eggs again, I'm going to be non-stop baking!
Okay, so we have actually not had as much snow as usual here and have been experiencing unusually warm weather this winter. Our chicks are due the 27th of April, so it will be well into May before I put them outside. I think we'll be pretty good there, but obviously we will use common sense if there are any weather issues. My dad is an electrician and the new coop will have some power running to it for any heat lamps, heated water dishes, or lights we might need out there too. And we live in the desert of Southern Utah, by the way, in a tiny little farming community at the base of a mountain. So lovely here.
Thanks for the suggestion on the cardboard corners, that should be easy to fix for them. Do you think a 4 foot box is big enough for that many chicks, and still have a warm side and cool side? We have baby chick waterers, but we usually have added something to it as was suggested. Marbles are a great idea, thanks. The chicks will be about 2-3 days old by the time they arrive, and there will be a few different breeds so they will likely grow at slightly different rates. I made sure to choose breeds that are docile and would get along well together, but I'm also aware that if some grow faster we may have need to separate the chicks to keep them from picking on each other too much. If that's the case, maybe I can just put a partition in the box. Or would that make it too difficult to keep temps at the right level? Also, is a thermometer a requirement inside the box? I've always had a mother hen so never worried too much.
I will purchase some extra paper towels to have on hand for the first few days. As for gro-gel, is that something that is needed after they've arrived? I was under the impression it was just to get them through the shipping. We have a couple of local farming stores in the next town over, I'm sure I can get all the supplies I need easily as long as I know what they are.

Oh, and thank you for the warm welcomes, I can't wait to be an official part of the chicken community again!

 

Oh, we don't normally need a heat lamp, just when I've had baby chicks to isolate and such (because I have purchased a few extra chicks before that weren't accepted by my mother hens and had to be integrated later on). We do usually have a light in there on a timer to keep the hens on a regular laying schedule, and heated water dishes for the winter. I guess once they are too big for the box in the house I can just put them straight into the coop. It has been insulated, so depending on the weather here come May, I might not need anything extra to keep the babies warm. And I will definitely look into the thermal panels as an alternative option, thank you! And I will also make sure they all are hydrated when they arrive. I'm sure I'll be taking pictures and posting many questions once they're here, as I'll probably need help distinguishing the breeds apart, lol.

Oh, and just for info for those you might be curious, the fire started in the chicken coop in the middle of the night. It was an electrical short in a power box that had nothing plugged into it at the time because it was summer. It was faulty, and with our chicken coop attached to three other buildings that were over 100 years old, everything went up very quickly. My dad is an electrician and he was working out of state at the time. When I called to tell him what happened he was extremely upset and he decided he was going to do all the new wiring to make sure everything was up to code and safe. He definitely doesn't want any other tragedies to happen, we were especially lucky! The fire was enormous and the flames could be seen from a neighboring town 15 miles away. Burned right through the power lines, which snapped in half and left our whole neighborhood without power until everything could be rewired late the next evening. We are very fortunate to live in a small community that all jumped to help in the middle of the night, saving our homes. The only lives lost were my 23 chickens, and it hurt me so deeply to see them suffer. We are absolutely taking extra precautions to prevent anything like this happening again. The new coop stands alone, and although I miss the beautiful old barns and the sentimentality of them, it's kind of nice to start fresh and be able to take all the extra steps to make everything perfect. Thank you all for your concern and well wishes, it was a very tough time for us. The healing has begun now that all the demolition is finished and new life is being brought in.

 

Can anyone tell me if it's okay to use wood shavings from the fruit trees in our yard? I know that Cedar shavings are bad for the chicks, and that Pine is okay. But are there other types that can harm the babies? We constantly have fresh piles of wood shavings from putting pruned limbs through the chipper, we'd love to use them if they are safe for the chicks.

 

We have several varieties of apple, plum, peach, pear, apricot and cherry if that helps. Also, we do chip our lilacs and currents, if that affects anything. Last year we had a huge snow storm that knocked lots of trees down, so there may also be some poplar in the mix of the older piles, but I have plenty of fresh fruit tree limbs ready to go through the chipper this weekend, so we can make sure to keep them separate if any of these types are dangerous.
