I asked about this in my local thread and got great responses but after looking at treatments and having time to examine the chick more, I think it may be something else. I just picked up these chicks today (my first ever chicks) from the post office. One of the four Brahmas I picked up has an injured leg. Please see photos that follow, it is the left leg. The leg is swollen and more red than the other I believe. It does a good job of stumbling around and has made good efforts towards eating and drinking and not being sat on. If advised I am willing to try a vet. Thank you in advance.
