So I have a hen, Lucy, a 1 yo buff Orpington, who mostly likely had an egg crack inside her. She got very sick and weak. I had to use antibiotics and tube feed her back to health. This started last Thursday, Friday was her at her worst (that afternoon we started antibiotics) and today she is acting so much better. She's able to stand longer, balance better, more talkative, preening, and finally eating by herself. However her comb seems to be getting blue... which I know is not a good thing so I'm looking for advice on whether or not I need to do something, if there's anything to do that is, or if it will pass as she continues to heal. I attatched some pictures below The first one of Lucy in early winter during her first molt. Next is Lucy before I started antibiotics, probably at the worst I've seen her on Friday afternoon. And the last two pictures are of her tonight. Maybe I'm just overreacting but I want to make sure I am doing everything possible for her. Thanks in advance for any help, suggestions, or links to articles!
