Our 6 month old Crested Polish Rooster started to fall down when eating. Found him on the ground, really weak legs - but not paralized legs (he uses them to scratch and tries to stand). Took him into the vet and they said he didn't have any infection, but we did 7 days of antibiotics and anti-inflamatories. He is eating and drinking fine, and sometimes tries to get up. He likes to stand and eat but has to lean on his box to do it. He has energy - just not the leg strength. One of the vets thought it was Mereks and the other didn't. I am really wondering about rickets? I noticed his feet are a little swollen, but he doesn't have any injury. He has a vision problem because of his crest - it's crazy thick and blocks his vision. I wonder if that has prevented him from eating as much as he should. The vet said he was a little skinny but not bad. I read about giving them children's liquid vitamin drops. I could only find Pedia Essentials Mult-Vitamin Drops. They don't have any iron in them and I am hoping I can use those? Any other suggestions?
