Well forget about the question about the hen laying the 1 egg only since I got her as a yb 2 years ago. She is gone . I looked into it my self and saw possibilities for a guy who had a lot of his hens laying only 1 egg . Pipa suggested paratyphoid , strep or e-coli . My hen was off when I got her . Free yb if I bought another so I took her . She went through the mill of antibiotics when she arrived and was vaccinated for para the last 2 years. It's not E-coli , 2 weeks ago she went through 5 days ACV . I do believe she may have been inbreed too far , but I am not familiar with that . I. Had put an egg under her and she hatched it and was over protective but got weak fast and couldn't handle it . Weirdest way I've seen . No fluffing up , no vomiting , wasn't on the floor , no warning , just exhaustion . That's the first time I lost a pigeon in a few years .
