This morning I noticed one of our easter eggers was limping a little. I figured there was a squabble over something as everyone has been stuck in the run quite a bit lately since they had lice. This evening the chicken is just laying there, unable to walk or use the leg now. I checked for bumble foot, everything looks clear. The crop is full, poo looks normal. Eyes clear, nostrils clear. Comb and wattles look normal. Ate some eggs and drank some water. I brought the chicken inside to the "hospital", he/she is just laying there, slightly to the left. The right leg is the one not working. What on earth do you think is going on?! Thanks.
