So, I made a mistake. I hatched some Plymouth Barred Rocks and some Blue Ameraucana chicks today. Before they fully dried off, I placed them all into the brooder under the warmth of the heat lamp. I assumed that, once fully dry, there would be distinct differences between breeds. I am growing concerned that I will not be able to tell the difference between the Blue Ameraucana chicks and the Plymouth Barred Rock chicks... As they continue to dry off and "puff out", they are only looking more similar! These chicks are for a couple family members and a dear friend, so its important to me to get the breeds right! There are quite a few more, on their way out, that I will mark before putting them into the brooder with the rest of them... but I have eight chicks currently that I need to decipher. Am I worrying too much? Maybe I can take them out into some natural light in the morning and see if I can tell... Any tips? They're all under a red heat lamp which could be throwing me off a bit.... From now on, I will be marking the different breeds, even if they look completely different.
