Possible Bite/Sting.

[barrelks]

So I was out gardening, with my chickens digging right next to me, when one about two feet from me let out a yelp, and fell to her side. Her legs are fully stretched out (can't walk), she has open beak and is panting, and not too happy being picked up.

Would this be a possible wasp/bee/spider bite (didn't see bee or find a stinger). Her belly feels warm. Also, is there any treatment. Chickens are my "pets", and this one is pals with my frizzle rooster who can't fly, so I will feel sorry for him if she dies. Any insight would be welcome. Thanks in advance.
