I have 3 roosters and about 25 laying hens. for the most part, i own at least 2 of each breed (RIR, LAV. ORP, BUFF, EE, OE, Sex link) and 1 ee roo, Blue CM, and creme legbar. why is it that last year when i hatched the EE's babies i got majority healthy chicks, but whenever i hatched a true mix this year the majority died/have deformities? i have a still air incubator and a turner that we tended to everyday. I put in about 38 eggs, 5-7 were infertile (31 left). Everyone else made it to hatching and out of the 31, 11 didnt hatch (20 left) 13 hatched on their own(yay) but 4 have jacked up feet?(7 left) (one i was able to fix he's ok) four pipped and started to bleed and died soon after. and the other 3 made it, but they are sooo jacked up im going to have to kill them. So WHY am i having SO many problems with these babies? Is it the mixed breed? Is it the age of my hens? My incubator? disease? Can somebody give me an idea of whats going on?
