Is there something that we can use to be able to tell our chicks apart? This is our first ever attempt at hatching. Also have questions about immunizations? Our first baby chick hatched this morning!! We were not expecting them to start hatching until Monday, but this little one decided to hatch 2 days early. It is a Ameraucana/Black Copper Maran cross from Zgoatlady. The kids and I built the bator out of a styrofoam cooler, fan and lamp and have lived on eggshells (ha ha) the entire time because the temps kept fluctuating up and down. We got 10 eggs and threw one away after about a week because it was obviously a dud. The shells of two are to thick to see developement but the rest have so far looked great, lots of growth and activity. I missed the entire event because we are out in Westport for the weekend. My 20 year old daughter has been taking care of it for us. Since this is our first attempt at hatching eggs I am totally unprepared for baby because I was planning on them hatching on Monday and was going to stop at Dells on the way home from the coast to buy everything that we needed then. One question I have is about immunizations. How do I do it? What do I give them? When do I give it? How much do I give? Where do I buy it from and how much does it cost? Ok that was more than one question. Would post photo but don't know how to, any suggestions?
