okay, under the beak and between the wattles is definitely swollen and her ears now look a bit bluish. she is still breathing alright and is alert and active in Ron's arms. I just gave her 0.5 ml of children's Benadryl. I am guessing that it needs to be given every 4 to 6 hours as the bottle says.
We went ahead and brought her inside for the night, hopefully she will stay stable and not get any worse.
As a side note I did remember that she is my chicken that likes to eat bees and wasps right out of the air! I did see some big bumble bees in the garden near their coop the other day. My guess is that she bit off more than she could chew!!
