I woke up this morning to let our girls out and noticed that our buff hen wasn't looking so good. Its been in the upper 90s here in Mia. and she really didin't want to eat like usual. The other girls ran out and started eating like normal. So I watched the buff and so just walked over to the shade and sat down. I went inside and got some bread and called her she slowly walked out and ate a few bites and went and sat back down. Yesterday she was fine. Whats up and any suggestions??
