Hi. Ive had my chickens for over a year now and recently we started hatching out of a homemade incubator. Weve hatched over 20 in the past 3 months with no problems until Thumbalina. She was born 3-4 days after her brothers and sisters. When we moved her out of the incubator we realised hshe was not walking. She hops one one foot most of the time. The other is bent at the hock and swollen, it almost looks like a scab. She sits or lays on the side that hurts. I can tell shes very uncomfortable most of the time ( peeping and hard to sleep) it tears me to pieces watching her. Any idea what this might be and anything I can do to help her.
